module Witch.From

-- | This type class is for converting values from some source
--   type into some other target type. The constraint
--   From source target means that you can convert from a
--   value of type source into a value of type target.
--   
--   This type class is for conversions that always succeed. If your
--   conversion sometimes fails, consider implementing TryFrom
--   instead.
class From source target

-- | This method implements the conversion of a value between types. At
--   call sites you may prefer to use into instead.
--   
--   
--   -- Avoid this:
--   from (x :: s)
--   
--   -- Prefer this (using [@TypeApplications@](https://downloads.haskell.org/ghc/9.6.1/docs/users_guide/exts/type_applications.html) language extension):
--   from @s x
--   
--   
--   The default implementation of this method simply calls coerce,
--   which works for types that have the same runtime representation. This
--   means that for newtypes you do not need to implement this
--   method at all. For example:
--   
--   
--   >>> newtype Name = Name String
--   
--   >>> instance From Name String
--   
--   >>> instance From String Name
--   
from :: From source target => source -> target
($dmfrom) :: (From source target, Coercible source target) => source -> target

module Witch.Generic

-- | This type class is used to implement generic conversions using the
--   Generically helper. This is an advanced use case. Most users
--   will not need to know about this type class. And even for those that
--   want to derive Generically, this type class should be an
--   implementation detail.
--   
--   This type class can convert between any two types as long as they have
--   Generic instances and they are structurally similar. For
--   example, if you define your own empty type you could convert it to the
--   typical Void type:
--   
--   
--   data Empty deriving Generic
--   deriving via Generically Void instance From Empty Void
--   
--   
--   Or your own unit type:
--   
--   
--   data Unit = MkUnit deriving Generic
--   deriving via Generically () instance From Unit ()
--   
--   
--   Note that this looks superficially similar to newtype Unit =
--   MkUnit () together with instance From Unit (), but that
--   goes through Coercible and requires the types to be
--   representationally equal. This approach (with Generically) only
--   requires the types to be structurally equal. In this case,
--   Unit is structurally equal to () since they both
--   have a single constructor with no arguments.
--   
--   This also works with arbitrary product types, like a custom pair type:
--   
--   
--   data Pair a b = MkPair a b deriving Generic
--   deriving via Generically (Pair c d)
--     instance (From a c, From b d) => From (a, b) (Pair c d)
--   
--   
--   Note that this can also convert the type variables as long as they
--   have From instances as well. This allows converting from
--   (Int, Int) to Pair Integer Integer in one step, for
--   example.
--   
--   And this works with arbitrary sum types as well:
--   
--   
--   data Result a b = Failure a | Success b deriving Generic
--   deriving via Generically (Result c d)
--     instance (From a c, From b d) => From (Either a b) (Result c d)
--   
--   
--   Note that these conversions are all structural not semantic.
--   That means if you had defined Result as Success b |
--   Failure a, then converting from Either would be "wrong".
--   Left would convert into Success and Right would
--   convert into Failure.

module Witch.TryFrom

-- | This type class is for converting values from some source
--   type into some other target type. The constraint

--   target, but that conversion may fail at runtime.
--   
--   This type class is for conversions that can sometimes fail. If your

-- | This method implements the conversion of a value between types. At

module Witch.Utility

-- | This is the same as id. This can be an ergonomic way to pin
--   down a polymorphic type in a function pipeline. For example:
--   
--   
--   -- Avoid this:
--   f . (\ x -> x :: Int) . g
--   
--   -- Prefer this:
--   f . as @Int . g
--   
as :: source -> source

-- | This is the same as from except that the type variables are in
--   the opposite order.
--   
--   
--   -- Avoid this:
--   from x :: t
--   
--   -- Prefer this:
--   into @t x
--   
into :: forall target source. From source target => source -> target

-- | This function converts from some source type into some
--   target type, applies the given function, then converts back
--   into the source type. This is useful when you have two types
--   that are isomorphic but some function that only works with one of
--   them.
--   
--   
--   -- Avoid this:
--   from @t . f . into @t
--   
--   -- Prefer this:
--   over @t f
--   
over :: forall target source. (From source target, From target source) => (target -> target) -> source -> source

-- | This function first converts from some source type into some
--   through type, and then converts that into some
--   target type. Usually this is used when writing From
--   instances. Sometimes this can be used to work around the lack of an
--   instance that should probably exist.
--   
--   
--   -- Avoid this:
--   from @u . into @u
--   
--   -- Prefer this:
--   via @u
--   
via :: forall through source target. (From source through, From through target) => source -> target

-- | This is the same as tryFrom except that the type variables are

--   
--   
--   -- Avoid this:
--   tryFrom x :: Either (TryFromException s t) t
--   
--   -- Prefer this:
--   tryInto @t x
--   
tryInto :: forall target source. TryFrom source target => source -> Either (TryFromException source target) target

-- | This is similar to via except that it works with TryFrom
--   instances instead. This function is especially convenient because
--   juggling the types in the TryFromException can be tedious.
--   
--   
--   -- Avoid this:
--   case tryInto @u x of
--     Left (TryFromException _ e) -> Left $ TryFromException x e

--   
tryVia :: forall through source target. (TryFrom source through, TryFrom through target) => source -> Either (TryFromException source target) target

-- | This function can be used to implement tryFrom with a function

--   
--   -- Avoid this:
--   tryFrom s = case f s of

--   tryFrom = maybeTryFrom f
--

-- | This function can be used to implement tryFrom with a function

--   
--   -- Avoid this:

--   -- Prefer this:
--   tryFrom = eitherTryFrom f
--   
eitherTryFrom :: Exception exception => (source -> Either exception target) -> source -> Either (TryFromException source target) target

-- | This function is like tryFrom except that it will throw an

-- | The Witch package is a library that allows you to confidently convert
--   values between various types. This module exports everything you need
--   to perform conversions or define your own. It is designed to be
--   imported unqualified, so getting started is as easy as:
--   
--   
--   >>> import Witch
--   
--   
--   In typical usage, the functions that you will use most often are
--   into for conversions that always succeed and tryInto for
--   conversions that sometimes fail.
--   
--   Please consider reading the blog post that announces this library:
--   https://taylor.fausak.me/2021/07/13/witch/
module Witch

-- | This type class is for converting values from some source
--   type into some other target type. The constraint
--   From source target means that you can convert from a
--   value of type source into a value of type target.
--   
--   This type class is for conversions that always succeed. If your
--   conversion sometimes fails, consider implementing TryFrom
--   instead.
class From source target

-- | This method implements the conversion of a value between types. At
--   call sites you may prefer to use into instead.
--   
--   
--   -- Avoid this:
--   from (x :: s)
--   
--   -- Prefer this (using [@TypeApplications@](https://downloads.haskell.org/ghc/9.6.1/docs/users_guide/exts/type_applications.html) language extension):
--   from @s x
--   
--   
--   The default implementation of this method simply calls coerce,
--   which works for types that have the same runtime representation. This
--   means that for newtypes you do not need to implement this
--   method at all. For example:
--   
--   
--   >>> newtype Name = Name String
--   
--   >>> instance From Name String
--   
--   >>> instance From String Name
--   
from :: From source target => source -> target
($dmfrom) :: (From source target, Coercible source target) => source -> target

-- | This is the same as from except that the type variables are in
--   the opposite order.
--   
--   
--   -- Avoid this:
--   from x :: t
--   
--   -- Prefer this:
--   into @t x
--   
into :: forall target source. From source target => source -> target

-- | This type class is for converting values from some source
--   type into some other target type. The constraint
--   TryFrom source target means that you may be able to
--   convert from a value of type source into a value of type
--   target, but that conversion may fail at runtime.
--   
--   This type class is for conversions that can sometimes fail. If your
--   conversion always succeeds, consider implementing From
--   instead.
class TryFrom source target

-- | This method implements the conversion of a value between types. At
--   call sites you may want to use tryInto instead.
--   
--   
--   -- Avoid this:
--   tryFrom (x :: s)
--   
--   -- Prefer this:
--   tryFrom @s
--   
--   
--   Consider using maybeTryFrom or eitherTryFrom to
--   implement this method.

tryInto :: forall target source. TryFrom source target => source -> Either (TryFromException source target) target

-- | This exception is thrown when a TryFrom conversion fails. It

-- | This function first converts from some source type into some
