Module xswag_base::code [−] [src]

This module contains types and functions to work on the raw source code.

Currently we do not distinguish between code-map and file-map, since one file always contains the whole code so far. However, this might change!

Structs

BytePos	Position within source specified by byte offset. This is not equal to `CharPos` thanks to UTF-8 and multibyte chars. This type always represents positions relative to the whole codemap.
ColIdx	Represents a column index.
FileMap	Stores the content of a file and keeps track of some position meta data, such as linebreaks.
LineIdx	Represents a line index.
Loc	Location within one file specified by line and column.
Span	A region within the source specified by first and last byte offset. `lo` byte is included in the span, `hi` byte is excluded.

Type do index one byte in a source code. It should be rather small, since it's used a lot.
