Module coord 

Compact coordinate representations shared across the engine and bindings.

Coord encodes an absolute cell position (row, column) in 64 bits with the same limits as Excel: 1,048,576 rows × 16,384 columns. RelativeCoord extends that layout with anchor flags that preserve the $A$1 semantics needed while parsing and adjusting formulas.

Structs

Coord

Absolute grid coordinate (row, column) with Excel-compatible bounds.

RelativeCoord

Relative coordinate (row, column) with anchor flags.

Enums

A1ParseError

Errors that can occur while parsing A1-style references.

CoordError

Errors returned when constructing coordinates from unchecked inputs.

Functions

col_index_from_letters_1based

Convert Excel column letters into a 1-based column index.

col_letters_from_1based

Convert a 1-based column index into its Excel letters (1 → “A”).

parse_a1_1based

Parse an A1-style reference and return 1-based coordinates plus absolute flags.
