Module source 

Structs

SpanIndex

Precomputed line-start byte offsets. The line is found in O(log n) (binary search over the line starts); the 1-based char column is then O(line length) (chars().count() over the line prefix, so multi-byte chars count as one).

Functions

lambda_anchors

(line, 1-based char col) of each lambda keyword token, in source order.

strip_bom

Strip a leading UTF-8 BOM (\u{feff}) from src, if present.
