    pub library_paths: Vec<PathBuf>,
    pub library_links: Vec<String>,
    pub linker_args: Vec<(LinkArgTarget, String)>,
    pub cfgs: Vec<String>,

}

Contains the parsed output of a custom build script.

Fields

library_paths: Vec<PathBuf>

Paths to pass to rustc with the -L flag.

library_links: Vec<String>

Names and link kinds of libraries, suitable for the -l flag.

linker_args: Vec<(LinkArgTarget, String)>

Linker arguments suitable to be passed to -C link-arg=<args>

cfgs: Vec<String>

Various --cfg flags to pass to the compiler.

check_cfgs: Vec<String>

Various --check-cfg flags to pass to the compiler.

env: Vec<(String, String)>

Additional environment variables to run the compiler with.

metadata: Vec<(String, String)>

Metadata to pass to the immediate dependencies.

rerun_if_changed: Vec<PathBuf>

Paths to trigger a rerun of this build script. May be absolute or relative paths (relative to package root).

rerun_if_env_changed: Vec<String>

Environment variables which, when changed, will cause a rebuild.

warnings: Vec<String>

Warnings generated by this build.

These are only displayed if this is a “local” package, -vv is used, or there is a build error for any target in this package.

Implementations

impl BuildOutput

pub fn parse_file( path: &Path, library_name: Option<String>, pkg_descr: &str, script_out_dir_when_generated: &Path, script_out_dir: &Path, extra_check_cfg: bool, nightly_features_allowed: bool, targets: &[Target] ) -> CargoResult<BuildOutput>

Like BuildOutput::parse but from a file path.

pub fn parse( input: &[u8], library_name: Option<String>, pkg_descr: &str, script_out_dir_when_generated: &Path, script_out_dir: &Path, extra_check_cfg: bool, nightly_features_allowed: bool, targets: &[Target] ) -> CargoResult<BuildOutput>

Parses the output instructions of a build script.

• pkg_descr — for error messages
• library_name — for determining if RUSTC_BOOTSTRAP should be allowed
• extra_check_cfg — for unstable feature -Zcheck-cfg

pub fn parse_rustc_flags( value: &str, whence: &str ) -> CargoResult<(Vec<PathBuf>, Vec<String>)>

Parses cargo:rustc-flags instruction.

pub fn parse_rustc_env( value: &str, whence: &str ) -> CargoResult<(String, String)>

Parses cargo:rustc-env instruction.

Trait Implementations

impl Clone for BuildOutput

fn clone(&self) -> BuildOutput

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BuildOutput

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for BuildOutput

fn default() -> BuildOutput

Returns the “default value” for a type.

impl Hash for BuildOutput

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.
