# Struct cargo::core::profiles::ProfileMaker

source ·

    struct ProfileMaker {
        default: Profile,
        toml: Option<TomlProfile>,
    }

Expand description

An object used for handling the profile hierarchy.

The precedence of profiles are (first one wins):

- Profiles in `.cargo/config` files (using same order as below).
- `[profile.dev.package.name]` – a named package.
- `[profile.dev.package."*"]` – this cannot apply to workspace members.
- `[profile.dev.build-override]` – this can only apply to `build.rs` scripts and their dependencies.
- `[profile.dev]`
- Default (hard-coded) values.

## Fields§

§`default: Profile`

The starting, hard-coded defaults for the profile.

§`toml: Option<TomlProfile>`

The TOML profile defined in `Cargo.toml` or config.

This is None if the user did not specify one, in which case the `default` is used. Note that the built-in defaults for test/bench/doc always set this since they need to declare the `inherits` value.

## Implementations§

source§

### impl ProfileMaker

source

#### fn new(default: Profile, toml: Option<TomlProfile>) -> ProfileMaker

Creates a new `ProfileMaker`.

Note that this does not process `inherits`, the caller is responsible for that.

source

#### fn get_profile( &self, pkg_id: Option<PackageId>, is_member: bool, is_for_host: bool ) -> Profile

Generates a new `Profile`.

## Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain `repr(...)` attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
