Enum MarkJump 

pub enum MarkJump {
    SameBuffer,
    CrossBuffer {
        buffer_id: u64,
        row: usize,
        col: usize,
    },
    Unset,
}

Return value from the engine’s try_goto_mark_* methods. Tells the caller (app layer) whether a cross-buffer switch is required.

• SameBuffer — cursor moved (or mark was unset → no-op) within the same buffer; no buffer switch needed.
• CrossBuffer — the mark lives in a different buffer. The app must switch to the slot whose buffer_id matches, then position the cursor at (row, col) using Editor::jump_cursor.
• Unset — mark not set; no action needed.

Trait Implementations

impl Clone for MarkJump

fn clone(&self) -> MarkJump

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MarkJump

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for MarkJump

fn eq(&self, other: &MarkJump) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
