Expand description

Collection of information about rustc and the host and target.

Fields§

§rustc: Rustc

Information about rustc itself.

§config: &'cfg Config

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 procedural macros, build scripts, etc.

§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<'cfg> RustcTargetData<'cfg>

source

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

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 cfgs 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.
