Struct rustc_span::source_map::FilePathMapping

pub struct FilePathMapping {
    mapping: Vec<(PathBuf, PathBuf)>,
    filename_display_for_diagnostics: FileNameDisplayPreference,
}

Fields

mapping: Vec<(PathBuf, PathBuf)>

filename_display_for_diagnostics: FileNameDisplayPreference

Implementations

impl FilePathMapping

pub fn empty() -> FilePathMapping

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

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)

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).

Trait Implementations

impl Clone for FilePathMapping

fn clone(&self) -> FilePathMapping

Returns a copy of the value.

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

Performs copy-assignment from source.

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
