impl CodeMap

fn new() -> CodeMap

fn new_filemap(&self, filename: FileName, src: String) -> Rc<FileMap>

fn new_imported_filemap(&self, filename: FileName, source_len: usize, file_local_lines: Vec<BytePos>, file_local_multibyte_chars: Vec<MultiByteChar>) -> Rc<FileMap>

Allocates a new FileMap representing a source file from an external crate. The source code of such an "imported filemap" is not available, but we still know enough to generate accurate debuginfo location information for things inlined from other crates.

fn mk_substr_filename(&self, sp: Span) -> String

fn lookup_char_pos(&self, pos: BytePos) -> Loc

Lookup source information about a BytePos

fn lookup_char_pos_adj(&self, pos: BytePos) -> LocWithOpt

fn span_to_string(&self, sp: Span) -> String

fn span_to_filename(&self, sp: Span) -> FileName

fn span_to_lines(&self, sp: Span) -> FileLines

fn span_to_snippet(&self, sp: Span) -> Result<String, SpanSnippetError>

fn get_filemap(&self, filename: &str) -> Rc<FileMap>

fn lookup_byte_offset(&self, bpos: BytePos) -> FileMapAndBytePos

For a global BytePos compute the local offset within the containing FileMap

fn bytepos_to_file_charpos(&self, bpos: BytePos) -> CharPos

Converts an absolute BytePos to a CharPos relative to the filemap and above.

fn record_expansion(&self, expn_info: ExpnInfo) -> ExpnId

fn with_expn_info<T, F>(&self, id: ExpnId, f: F) -> T where F: FnOnce(Option<&ExpnInfo>) -> T

fn span_allows_unstable(&self, span: Span) -> bool

Check if a span is "internal" to a macro in which #[unstable] items can be used (that is, a macro marked with #[allow_internal_unstable]).
