Struct partiql_source_map::location::CharOffset

pub struct CharOffset(pub u32);

A 0-indexed char offset, relative to some other position.

This value represents the number of unicode codepoints seen, so will differ from ByteOffset for a given location in a &str if the string contains non-ASCII unicode characters

Tuple Fields

0: u32
