Struct CompositeBuffer 

pub struct CompositeBuffer {
    pub id: BufferId,
    pub name: String,
    pub layout: CompositeLayout,
    pub sources: Vec<SourcePane>,
    pub alignment: LineAlignment,
    pub active_pane: usize,
    pub mode: String,
    pub initial_focus_hunk: Option<usize>,
}

A buffer that composes content from multiple source buffers

Fields

id: BufferId

Unique ID for this composite buffer

name: String

Display name (shown in tab bar)

layout: CompositeLayout

Layout mode for this composite

sources: Vec<SourcePane>

Source buffer configurations

alignment: LineAlignment

Line alignment map (for side-by-side diff) Maps display_line -> (left_source_line, right_source_line)

active_pane: usize

Which pane currently has focus (for input routing)

mode: String

Mode for keybindings

initial_focus_hunk: Option<usize>

When set, the first render will scroll to center this hunk (0-indexed) and then clear this field. This avoids timing issues where imperative scroll commands depend on render-created state (viewport, view state).
