Struct OperatorContext 

pub struct OperatorContext<'a> {
    pub kernel: &'a KernelContext,
    pub registers: &'a mut RegisterBank,
    pub clipboard_history: &'a mut HistoryRing,
    pub buffer_id: BufferId,
    pub register: Register,
    pub count: usize,
    pub cursor_position: Position,
    pub cursor_after: Option<Position>,
}

Context passed to operator execution.

Fields

kernel: &'a KernelContext

Kernel context for accessing services.

registers: &'a mut RegisterBank

Per-client register storage (#515).

clipboard_history: &'a mut HistoryRing

Per-client clipboard history (#515).

buffer_id: BufferId

Buffer to operate on.

register: Register

Target register for operator output.

count: usize

Count prefix (e.g., 3dd has count 3).

cursor_position: Position

Cursor position before operator execution (for undo tracking).

This is passed from the caller who has access to window state. Used to record cursor_before for undo.

cursor_after: Option<Position>

Cursor position the operator requests after execution.

Set by operators during execute() to communicate desired post-operation cursor position. None means the caller applies a default clamped fallback. This makes OperatorContext a bidirectional channel — consistent with registers and clipboard_history which are also mutated during execute.
