Expand description

Collection of information about `rustc` and the host and target.

## Fields§

§`rustc: Rustc`

Information about `rustc` itself.

§`gctx: &'gctx GlobalContext`

Config

§`requested_kinds: Vec<CompileKind>`§`host_config: TargetConfig`

Build information for the “host”, which is information about when `rustc` is invoked without a `--target` flag. This is used for selecting a linker, and applying link overrides.

The configuration read into this depends on whether or not `target-applies-to-host=true`.

§`host_info: TargetInfo`

Information about the host platform.

§`target_config: HashMap<CompileTarget, TargetConfig>`

Build information for targets that we’re building for.

§`target_info: HashMap<CompileTarget, TargetInfo>`

Information about the target platform that we’re building for.

## Implementations§

source§

### impl<'gctx> RustcTargetData<'gctx>

source

#### pub fn new( ws: &Workspace<'gctx>, requested_kinds: &[CompileKind], ) -> CargoResult<RustcTargetData<'gctx>>

source

#### pub fn merge_compile_kind(&mut self, kind: CompileKind) -> CargoResult<()>

Insert `kind` into our `target_info` and `target_config` members if it isn’t present yet.

source

#### pub fn short_name<'a>(&'a self, kind: &'a CompileKind) -> &'a str

Returns a “short” name for the given kind, suitable for keying off configuration in Cargo or presenting to users.

source

#### pub fn dep_platform_activated( &self, dep: &Dependency, kind: CompileKind, ) -> bool

Whether a dependency should be compiled for the host or target platform, specified by `CompileKind`.

source

#### pub fn cfg(&self, kind: CompileKind) -> &[Cfg]

Gets the list of `cfg`s printed out from the compiler for the specified kind.

source

#### pub fn info(&self, kind: CompileKind) -> &TargetInfo

Information about the given target platform, learned by querying rustc.

##### §Panics

Panics, if the target platform described by `kind` can’t be found. See `get_info` for a non-panicking alternative.

source

#### pub fn get_info(&self, kind: CompileKind) -> Option<&TargetInfo>

Information about the given target platform, learned by querying rustc.

Returns `None` if the target platform described by `kind` can’t be found.

source

#### pub fn target_config(&self, kind: CompileKind) -> &TargetConfig

Gets the target configuration for a particular host or target.

source

#### pub fn script_override( &self, lib_name: &str, kind: CompileKind, ) -> Option<&BuildOutput>

If a build script is overridden, this returns the `BuildOutput` to use.

`lib_name` is the `links` library name and `kind` is whether it is for Host or Target.

## 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.
