Struct BufferStateGuard 

pub struct BufferStateGuard<S: Send + Sync + 'static> { /* private fields */ }

Drops a buffer’s state entry when its mode deactivates.

Handler registrations are no longer per-activation anywhere in this crate, so what is left to unwind is the state entry, the published view, and (MG.14) the headerline’s virtual-row provider.

Implementations

impl<S: Send + Sync + 'static> BufferStateGuard<S>

pub fn new(states: Arc<BufferStates<S>>, buffer: BufferId) -> Self

pub fn with_views(self, views: MagitViewsHandle) -> Self

Also unpublish this buffer’s MagitView on drop.

pub fn with_headerline( self, registration: Option<HeaderlineRegistration>, ) -> Self

Also tear down this buffer’s headerline on drop. None (a harness with no virtual-row registrar) is a no-op.

Trait Implementations

impl<S: Send + Sync + 'static> Drop for BufferStateGuard<S>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
