## Packages

# Enum Packages

Source

    pub enum Packages {
        Default,
        All(Vec<String>),
        OptOut(Vec<String>),
        Packages(Vec<String>),
    }

Expand description

Represents the selected packages that will be built.

Generally, it represents the combination of all `-p` flag. When working within a workspace, `--exclude` and `--workspace` flags also contribute to it.

## Variants§

§

### Default

Packages selected by default. Usually means no flag provided.

§

### All(Vec<String>)

Opt in all packages.

As of the time of this writing, it only works on opting in all workspace members. Keeps the packages passed in to verify that they exist in the workspace.

§

### OptOut(Vec<String>)

Opt out of packages passed in.

As of the time of this writing, it only works on opting out workspace members.

§

### Packages(Vec<String>)

A sequence of hand-picked packages that will be built. Normally done by `-p` flag.

## Implementations§

Source§

### impl Packages

Source

#### pub fn from_flags( all: bool, exclude: Vec<String>, package: Vec<String>, ) -> CargoResult<Self>

Creates a `Packages` from flags which are generally equivalent to command line flags.

Source

#### pub fn to_package_id_specs( &self, ws: &Workspace<'_>, ) -> CargoResult<Vec<PackageIdSpec>>

Converts selected packages to `PackageIdSpec`s.

Source

#### pub fn get_packages<'ws>( &self, ws: &'ws Workspace<'_>, ) -> CargoResult<Vec<&'ws Package>>

Gets a list of selected `Package`s.

Source

#### pub fn needs_spec_flag(&self, ws: &Workspace<'_>) -> bool

Returns whether or not the user needs to pass a `-p` flag to target a specific package in the workspace.
