Struct SourceMap 

pub struct SourceMap {
    files: Vec<SourceFile>,
}

Registry of source files participating in a single compilation/run.

Diagnostics carry a FileId (via their Span); the renderer looks up the file’s path and source via this map.

Fields

files: Vec<SourceFile>

Implementations

impl SourceMap

pub fn new() -> Self

pub fn add_file( &mut self, path: impl Into<PathBuf>, source: impl Into<String>, ) -> FileId

Register a file and return its FileId.

Panics

Panics if the number of registered files exceeds u32::MAX.

pub fn get(&self, file_id: FileId) -> Option<&SourceFile>

pub fn path_of(&self, file_id: FileId) -> Option<&Path>

pub fn source_of(&self, file_id: FileId) -> Option<&str>
