Struct RustcTargetData 

pub struct RustcTargetData<'gctx> {
    pub rustc: Rustc,
    pub gctx: &'gctx GlobalContext,
    requested_kinds: Vec<CompileKind>,
    host_config: TargetConfig,
    host_info: TargetInfo,
    target_config: HashMap<CompileTarget, TargetConfig>,
    target_info: HashMap<CompileTarget, TargetInfo>,
}

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

impl<'gctx> RustcTargetData<'gctx>

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

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.

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.

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.

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

Gets the list of cfgs printed out from the compiler for the specified kind.

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.

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.

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

Gets the target configuration for a particular host or target.

pub fn get_unsupported_std_targets(&self) -> Vec<&str>

pub fn requested_kinds(&self) -> &[CompileKind]

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.
