Struct LineIndex 

pub struct LineIndex { /* private fields */ }

Precomputed newline codepoint-offsets for O(log n) line lookup — same idea as pylatexenc’s internal line-boundary cache.

Implementations

impl LineIndex

pub fn new(chars: &[char]) -> Self

pub fn with_offset(chars: &[char], offset: u32) -> Self

Like Self::new, but every lineno_colno result has offset added to its line. pos arguments stay relative to chars as given (fragment-local), not to the offset target.

pub fn lineno_colno(&self, pos: usize) -> (u32, u32)

Returns (1-based line, 0-based column), both in codepoints.
