A single source in the CodeMap.


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>

True if the name field above has been modified by --remap-path-prefix

The unmapped path of the file that the source came from. Set to None if the FileMap was imported from an external crate.

Indicates which crate this FileMap was imported from.

The complete source code

The source code's hash

The external source code (used for external crates, which will have a None value as self.src.

The start position of this source in the CodeMap

The end position of this source in the CodeMap

Locations of lines beginnings in the source code

Locations of multi-byte characters in the source code

Width of characters that are not narrow in the source code

A hash of the filename, used for speeding up the incr. comp. hashing.


impl FileMap

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 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.

Return the BytePos of the beginning of the current line.

Add externally loaded source. If the hash of the input doesn't match or no input is supplied via None, it is interpreted as an error and the corresponding enum variant is set. The return value signifies whether some kind of source is present.

Get a line from the list of pre-computed line-beginnings. The line number here is 0-based.

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.
