LocalPath(PathBuf)

§

Remapped

Fields

§local_path: Option<PathBuf>

local_path is the (host-dependent) local path to the file. This is None if the file was imported from another crate

§virtual_name: PathBuf

virtual_name is the stable path rustc will store internally within build artifacts.

For remapped paths (namely paths into libstd that have been mapped to the appropriate spot on the local host’s file system, and local file system paths that have been remapped with FilePathMapping),

Implementations§

source§

impl RealFileName

source

pub fn local_path(&self) -> Option<&Path>

Returns the path suitable for reading from the file system on the local host, if this information exists. Avoid embedding this in build artifacts; see remapped_path_if_available() for that.

source

pub fn into_local_path(self) -> Option<PathBuf>

Returns the path suitable for reading from the file system on the local host, if this information exists. Avoid embedding this in build artifacts; see remapped_path_if_available() for that.

source

pub fn remapped_path_if_available(&self) -> &Path

Returns the path suitable for embedding into build artifacts. This would still be a local path if it has not been remapped. A remapped path will not correspond to a valid file system path: see local_path_if_available() for something that is more likely to return paths into the local host file system.

source

pub fn local_path_if_available(&self) -> &Path

Returns the path suitable for reading from the file system on the local host, if this information exists. Otherwise returns the remapped name. Avoid embedding this in build artifacts; see remapped_path_if_available() for that.
