Crate squawk_line_index 

See LineIndex.

Forked from rust-analyzer’s line-index. Our changes are tagged with a SQUAWK: comment so they can be reapplied when resyncing with upstream:

• \r and \r\n start a new line, not just \n. Upstream only breaks on \n, which leaves a classic Mac file looking like one enormous line.
• [newlines] adds helpers upstream doesn’t have.

Structs

Line

LineCol

(line, column) information in the native, UTF-8 encoding.

LineIndex

Maps flat TextSize offsets to/from (line, column) representation.

NewlineWithTrailingNewline

Like UniversalNewlineIterator, but includes a trailing newline as an empty line.

TextRange

A range in text, represented as a pair of TextSize.

TextSize

A measure of text length. Also, equivalently, an index into text.

UniversalNewlineIterator

Like str::lines, but accommodates LF, CRLF, and CR line endings, the latter of which are not supported by str::lines.

WideLineCol

(line, column) information in wide encodings.

Enums

LineEnding

The line ending style used in Python source code. See https://docs.python.org/3/reference/lexical_analysis.html#physical-lines

WideEncoding

A kind of wide character encoding.

Traits

UniversalNewlines

Extension trait for str that provides a UniversalNewlineIterator.

Functions
