Struct ScrollbarRowCache 

pub struct ScrollbarRowCache {
    pub buffer_version: u64,
    pub viewport_width: u16,
    pub wrap_indent: bool,
    pub total_visual_rows: usize,
    pub top_byte: usize,
    pub top_visual_row: usize,
    pub top_view_line_offset: usize,
    pub valid: bool,
}

Cache for scrollbar visual row counts. Avoids re-wrapping every line in the file on each render frame.

Fields

buffer_version: u64

Buffer version when this cache was computed

viewport_width: u16

Viewport width used for wrapping

wrap_indent: bool

Whether wrap indent was enabled

total_visual_rows: usize

Cached total visual rows

top_byte: usize

top_byte → top_visual_row mapping from last computation

top_visual_row: usize

Cached top visual row

top_view_line_offset: usize

top_view_line_offset used in the computation

valid: bool

Whether the cache has been populated at least once
