Struct cargo::core::compiler::TargetInfo

pub struct TargetInfo {
    pub sysroot: PathBuf,
    pub sysroot_host_libdir: PathBuf,
    pub sysroot_target_libdir: PathBuf,
    pub rustflags: Vec<String>,
    pub rustdocflags: Vec<String>,
    /* private fields */
}

Information about the platform target gleaned from querying rustc.

RustcTargetData keeps several of these, one for the host and the others for other specified targets. If no target is specified, it uses a clone from the host.

Fields

sysroot: PathBuf

Path to the sysroot.

sysroot_host_libdir: PathBuf

Path to the “lib” or “bin” directory that rustc uses for its dynamic libraries.

sysroot_target_libdir: PathBuf

Path to the “lib” directory in the sysroot which rustc uses for linking target libraries.

rustflags: Vec<String>

Extra flags to pass to rustc, see [extra_args].

rustdocflags: Vec<String>

Extra flags to pass to rustdoc, see [extra_args].

Implementations

impl TargetInfo

pub fn new( config: &Config, requested_kinds: &[CompileKind], rustc: &Rustc, kind: CompileKind ) -> CargoResult<TargetInfo>

Learns the information of target platform from rustc invocation(s).

Generally, the first time calling this function is expensive, as it may query rustc several times. To reduce the cost, output of each rustc invocation is cached by Rustc::cached_output.

Search Tricky to learn why querying rustc several times is needed.

pub fn cfg(&self) -> &[Cfg]

All the target Cfg settings.

pub fn rustc_outputs( &self, mode: CompileMode, target_kind: &TargetKind, target_triple: &str ) -> CargoResult<(Vec<FileType>, Vec<CrateType>)>

Returns all the file types generated by rustc for the given mode/target_kind.

The first value is a Vec of file types generated, the second value is a list of CrateTypes that are not supported by the given target.

pub fn supports_debuginfo_split(&self, split: InternedString) -> bool

Checks if the debuginfo-split value is supported by this target

Trait Implementations

impl Clone for TargetInfo

fn clone(&self) -> TargetInfo

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
