}Expand description
A single source in the CodeMap.
Fields§
§name: FileNameThe name of the file that the source came from, source that doesn’t
originate from files has names between angle brackets by convention,
e.g. <anon>
name_was_remapped: boolTrue if the name field above has been modified by -Zremap-path-prefix
crate_of_origin: u32Indicates which crate this FileMap was imported from.
src: Option<Rc<String>>The complete source code
start_pos: BytePosThe start position of this source in the CodeMap
end_pos: BytePosThe end position of this source in the CodeMap
lines: RefCell<Vec<BytePos>>Locations of lines beginnings in the source code
multibyte_chars: RefCell<Vec<MultiByteChar>>Locations of multi-byte characters in the source code
Implementations§
Source§impl FileMap
impl FileMap
Sourcepub fn next_line(&self, pos: BytePos)
pub fn next_line(&self, pos: BytePos)
EFFECT: register a start-of-line offset in the table of line-beginnings. UNCHECKED INVARIANT: these offsets must be added in the right order and must be in the right places; there is shared knowledge about what ends a line between this file and parse.rs WARNING: pos param here is the offset relative to start of CodeMap, and CodeMap will append a newline when adding a filemap without a newline at the end, so the safe way to call this is with value calculated as filemap.start_pos + newline_offset_relative_to_the_start_of_filemap.
Sourcepub fn get_line(&self, line_number: usize) -> Option<&str>
pub fn get_line(&self, line_number: usize) -> Option<&str>
get a line from the list of pre-computed line-beginnings. line-number here is 0-based.
pub fn record_multibyte_char(&self, pos: BytePos, bytes: usize)
pub fn is_real_file(&self) -> bool
pub fn is_imported(&self) -> bool
pub fn byte_length(&self) -> u32
pub fn count_lines(&self) -> usize
Sourcepub fn lookup_line(&self, pos: BytePos) -> Option<usize>
pub fn lookup_line(&self, pos: BytePos) -> Option<usize>
Find the line containing the given position. The return value is the
index into the lines array of this FileMap, not the 1-based line
number. If the filemap is empty or the position is located before the
first line, None is returned.
