Struct PaneHistoryRow 

pub struct PaneHistoryRow {
    pub index: u32,
    pub label: String,
    pub line: u32,
    pub is_current: bool,
}

PBH.5: one row of the active pane’s buffer trail, flattened for the picker.

Carries the trail index rather than a buffer id: the same buffer can appear at several points in a trail, and accepting the third stop must land on the third stop, not the first occurrence.

Fields

index: u32

Position in the trail, oldest-first. The accept payload.

label: String

Display label — the buffer’s name or path.

line: u32

Line the trail recorded for this stop (1-based for display).

is_current: bool

Whether the walk cursor currently sits on this entry.
