Enum BackResponse 

pub enum BackResponse {
    Proceed,
    Handled,
}

What a Stack::on_back guard returns for one back-like event (a native back gesture/button, or nav_back). Programmatic path writes are NOT guarded — the guard is a policy on the user’s back affordance, matching Jetpack Compose’s BackHandler (docs/navigation.md).

Variants

Proceed

Let the pop happen now.

Handled

Consume the back — the pop does NOT happen. Stash the BackRequest and call BackRequest::proceed later (e.g. after a confirmation dialog) to perform the pop.

Trait Implementations

impl Clone for BackResponse

fn clone(&self) -> BackResponse

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BackResponse

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

impl PartialEq for BackResponse

fn eq(&self, other: &BackResponse) -> 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.
