Struct HighlightCache 

Source 
pub struct HighlightCache { /* private fields */ }
Expand description

Pre-computed syntax highlighting cache. Keyed by (file_idx, hunk_idx, line_idx) -> Vec<(ratatui Style, text)>.

Implementations§

Source§

impl HighlightCache

Source

pub fn new(diff_data: &DiffData, syntect_theme_name: &str) -> Self

Pre-compute syntax highlighting for all diff lines. syntect_theme_name should be a key present in syntect’s default ThemeSet (e.g. “base16-ocean.dark” or “base16-ocean.light”).

Source

pub fn get( &self, file_idx: usize, hunk_idx: usize, line_idx: usize, ) -> Option<&Vec<(Style, String)>>

Look up cached highlighted spans for a specific line.
