Expand description
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§
§crate_type_process: ProcessBuilder
A base process builder for discovering crate type information. In particular, this is used to determine the output filename prefix and suffix for a crate type.
crate_types: RefCell<HashMap<CrateType, Option<(String, String)>>>
Cache of output filename prefixes and suffixes.
The key is the crate type name (like cdylib
) and the value is
Some((prefix, suffix))
, for example libcargo.so
would be
Some(("lib", ".so"))
. The value is None
if the crate type is not
supported.
cfg: Vec<Cfg>
cfg
information extracted from rustc --print=cfg
.
support_split_debuginfo: Vec<String>
Supported values for -Csplit-debuginfo=
flag, queried from rustc
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§
source§impl TargetInfo
impl TargetInfo
sourcepub fn new(
config: &Config,
requested_kinds: &[CompileKind],
rustc: &Rustc,
kind: CompileKind
) -> CargoResult<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.
fn not_user_specific_cfg(cfg: &CargoResult<Cfg>) -> bool
sourcefn file_types(
&self,
crate_type: &CrateType,
flavor: FileFlavor,
target_triple: &str
) -> CargoResult<Option<Vec<FileType>>>
fn file_types( &self, crate_type: &CrateType, flavor: FileFlavor, target_triple: &str ) -> CargoResult<Option<Vec<FileType>>>
Returns the list of file types generated by the given crate type.
Returns None
if the target does not support the given crate type.
fn discover_crate_type( &self, crate_type: &CrateType ) -> CargoResult<Option<(String, String)>>
sourcepub fn rustc_outputs(
&self,
mode: CompileMode,
target_kind: &TargetKind,
target_triple: &str
) -> CargoResult<(Vec<FileType>, Vec<CrateType>)>
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.
fn calc_rustc_outputs( &self, target_kind: &TargetKind, target_triple: &str ) -> CargoResult<(Vec<FileType>, Vec<CrateType>)>
sourcepub fn supports_debuginfo_split(&self, split: InternedString) -> bool
pub fn supports_debuginfo_split(&self, split: InternedString) -> bool
Checks if the debuginfo-split value is supported by this target

attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
