Struct syntex_pos::FileMap
[−]
[src]
pub struct FileMap { pub name: FileName, pub abs_path: Option<FileName>, pub src: Option<Rc<String>>, pub start_pos: BytePos, pub end_pos: BytePos, pub lines: RefCell<Vec<BytePos>>, pub multibyte_chars: RefCell<Vec<MultiByteChar>>, }
A single source in the CodeMap.
Fields
name: FileName
The 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>
abs_path: Option<FileName>
The absolute path of the file that the source came from.
src: Option<Rc<String>>
The complete source code
start_pos: BytePos
The start position of this source in the CodeMap
end_pos: BytePos
The 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
Methods
impl FileMap
[src]
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.
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.
