Implementations

impl SourceCode

pub fn codemap(&self) -> Ref<'_, CodeMap>

Access a read-only reference to the codemap.

fn codemap_mut(&self) -> RefMut<'_, CodeMap>

Access a writable reference to the codemap.

pub fn add_file(&self, name: String, code: String) -> Arc<File>

pub fn source_slice(&self, span: Span) -> Ref<'_, str>

Returns the literal source slice of the given span.

pub fn get_file(&self, span: Span) -> Arc<File>

Returns the reference to the file structure that a given span is in.
