Struct SourceMap 

pub struct SourceMap { /* private fields */ }

File-level attribution: for each contributed segment of the combined source, its byte range, originating file, and (for byte-intact segments) the offset-within-file mapping — so a diagnostic on the combined blob is attributed to the user’s own file and line.

Implementations

impl SourceMap

pub fn file_for(&self, offset: usize) -> Option<&Path>

The file that contributed the text at offset in the combined source.

pub fn locate(&self, offset: usize) -> Option<Located<'_>>

Resolve offset back to its originating file, offset-within-file, and whether that mapping is exact. None when offset is outside every segment (e.g. inside spliced trailing whitespace at the very end).

Trait Implementations

impl Debug for SourceMap

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

Formats the value using the given formatter.

impl Default for SourceMap

fn default() -> SourceMap

Returns the “default value” for a type.
