Methods
impl CodeMap
fn new() -> CodeMap
fn with_file_loader(file_loader: Box<FileLoader>) -> CodeMap
fn file_exists(&self, path: &Path) -> bool
fn load_file(&self, path: &Path) -> Result<Rc<FileMap>>
fn new_filemap(&self, filename: FileName, src: String) -> Rc<FileMap>
Creates a new filemap without setting its line information. If you don't intend to set the line information yourself, you should use new_filemap_and_lines.
fn new_filemap_and_lines(&self, filename: &str, src: &str) -> Rc<FileMap>
Creates a new filemap and sets its line information.
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) -> FileLinesResult
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.
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]).
