Implementations§

source§

impl FilePathMapping

source

pub fn empty() -> FilePathMapping

source

pub fn new(mapping: Vec<(PathBuf, PathBuf)>) -> FilePathMapping

source

pub fn map_prefix<'a>( &'a self, path: impl Into<Cow<'a, Path>> ) -> (Cow<'a, Path>, 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.

source

fn map_filename_prefix(&self, file: &FileName) -> (FileName, bool)

source

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).

source

fn reverse_map_prefix_heuristically(&self, path: &Path) -> Option<PathBuf>

Attempts to (heuristically) reverse a prefix mapping.

Returns Some if there is exactly one mapping where the “to” part is a prefix of path and has at least one non-empty Normal component. The component restriction exists to avoid reverse mapping overly generic paths like / or .).

This is a heuristic and not guaranteed to return the actual original path! Do not rely on the result unless you have other means to verify that the mapping is correct (e.g. by checking the file content hash).
