Struct IdStackToken 

pub struct IdStackToken<'a> { /* private fields */ }

Tracks an ID pushed to the ID stack that can be popped by calling .pop() or by dropping. See crate::Ui::push_id for more details.

Drop order

Tokens sharing this native resource stack must finish in reverse creation order. Window- or table-local tokens must also finish in their originating scope. Prefer the corresponding closure helper when available. Invalid use panics before FFI, with cleanup deferred when the original scope can be restored safely.

Implementations

impl<'a> IdStackToken<'a>

pub fn end(self)

Pops a change from the ID stack

Panics

Panics before FFI if a later token on the same native resource stack is active or this token is no longer in its originating native scope.

impl IdStackToken<'_>

pub fn pop(self)

Pops a change from the ID stack.

Panics

Panics under the same conditions as Self::end.

Trait Implementations

impl Drop for IdStackToken<'_>

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.
