pub fn new_filemap(&self, filename: FileName, src: String) -> Lrc<FileMap>[src]
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.
pub fn new_filemap_and_lines(&self, filename: &Path, src: &str) -> Lrc<FileMap>[src]
Creates a new filemap and sets its line information.

file_local_multibyte_chars: Vec<MultiByteChar>,
file_local_non_narrow_chars: Vec<NonNarrowChar>
) -> Lrc<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.
pub fn mk_substr_filename(&self, sp: Span) -> String[src]
pub fn doctest_offset_line(&self, orig: usize) -> usize[src]
pub fn lookup_char_pos(&self, pos: BytePos) -> Loc[src]
Lookup source information about a BytePos
pub fn lookup_line(&self, pos: BytePos) -> Result<FileMapAndLine, Lrc<FileMap>>[src]
pub fn lookup_char_pos_adj(&self, pos: BytePos) -> LocWithOpt[src]
pub fn merge_spans(&self, sp_lhs: Span, sp_rhs: Span) -> Option<Span>[src]
Returns Some(span), a union of the lhs and rhs span. The lhs must precede the rhs. If
there are gaps between lhs and rhs, the resulting union will cross these gaps.
For this to work, the spans have to be:
- the ctxt of both spans much match
- the lhs span needs to end on the same line the rhs span begins
- the lhs span must start at or before the rhs span
pub fn span_to_string(&self, sp: Span) -> String[src]
pub fn span_to_filename(&self, sp: Span) -> FileName[src]
pub fn span_to_unmapped_path(&self, sp: Span) -> FileName[src]
pub fn is_multiline(&self, sp: Span) -> bool[src]
pub fn span_to_lines(&self, sp: Span) -> FileLinesResult[src]
pub fn span_to_snippet(&self, sp: Span) -> Result<String, SpanSnippetError>[src]
Return the source snippet as String corresponding to the given Span
pub fn span_to_prev_source(&self, sp: Span) -> Result<String, SpanSnippetError>[src]
Return the source snippet as String before the given Span
pub fn span_until_char(&self, sp: Span, c: char) -> Span[src]
Given a Span, try to get a shorter span ending before the first occurrence of c char
pub fn span_extend_to_prev_char(&self, sp: Span, c: char) -> Span[src]
Extend the given Span to just after the previous occurrence of c. Return the same span
if no character could be found or if an error occurred while retrieving the code snippet.
pub fn span_extend_to_prev_str(&self, sp: Span, pat: &str) -> Span[src]
Extend the given Span to just after the previous occurrence of pat. Return the same span
if no character could be found or if an error occurred while retrieving the code snippet.
pub fn span_until_non_whitespace(&self, sp: Span) -> Span[src]
Given a Span, get a new Span covering the first token and all its trailing whitespace or
the original Span.
If sp points to "let mut x", then a span pointing at "let " will be returned.
pub fn span_until_whitespace(&self, sp: Span) -> Span[src]
Given a Span, get a new Span covering the first token without its trailing whitespace or
the original Span in case of error.
If sp points to "let mut x", then a span pointing at "let" will be returned.
pub fn span_through_char(&self, sp: Span, c: char) -> Span[src]
Given a Span, try to get a shorter span ending just after the first occurrence of char
c.
pub fn def_span(&self, sp: Span) -> Span[src]
pub fn end_point(&self, sp: Span) -> Span[src]
Returns a new span representing just the end-point of this span
pub fn next_point(&self, sp: Span) -> Span[src]
Returns a new span representing the next character after the end-point of this span
pub fn get_filemap(&self, filename: &FileName) -> Option<Lrc<FileMap>>[src]
pub fn lookup_byte_offset(&self, bpos: BytePos) -> FileMapAndBytePos[src]
For a global BytePos compute the local offset within the containing FileMap
pub fn bytepos_to_file_charpos(&self, bpos: BytePos) -> CharPos[src]
Converts an absolute BytePos to a CharPos relative to the filemap.
