Struct Owner 

pub struct Owner(/* private fields */);

A unique lifetime owner. Commit starts registered work; drop disposes it. Handles are weak and cannot extend the lifetime. This is single-threaded.

Implementations

impl Owner

pub fn new() -> Self

Prepare a root lifetime. Work waits for Self::commit.

pub fn child(parent: &OwnerHandle) -> Self

Prepare a child. It activates only after both it and its ancestors commit. An expired parent produces a disposed child.

pub fn handle(&self) -> OwnerHandle

pub fn commit(&self)

Commit once preparation succeeds. Idempotent; cannot revive disposal.

pub fn dispose(&self)

Invalidate the whole subtree before calling any cleanup. Reentrant and idempotent. Cleanup is synchronous; it cannot await task termination.

Trait Implementations

impl Default for Owner

fn default() -> Self

Returns the “default value” for a type.

impl Drop for Owner

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.
