Implementations
sourceimpl FilePathMapping
impl FilePathMapping
pub fn empty() -> FilePathMapping
pub fn new(mapping: Vec<(PathBuf, PathBuf)>) -> FilePathMapping
sourcepub fn map_prefix(&self, path: PathBuf) -> (PathBuf, bool)
pub fn map_prefix(&self, path: PathBuf) -> (PathBuf, bool)
Applies any path prefix substitution as defined by the mapping. The return value is the remapped path and a boolean indicating whether the path was affected by the mapping.
fn map_filename_prefix(&self, file: &FileName) -> (FileName, bool)
sourcepub fn to_embeddable_absolute_path(
&self,
file_path: RealFileName,
working_directory: &RealFileName
) -> RealFileName
pub fn to_embeddable_absolute_path(
&self,
file_path: RealFileName,
working_directory: &RealFileName
) -> RealFileName
Expand a relative path to an absolute path with remapping taken into account. Use this when absolute paths are required (e.g. debuginfo or crate metadata).
The resulting RealFileName
will have its local_path
portion erased if
possible (i.e. if there’s also a remapped path).

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