Struct Completion 

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

A completion handle for message-based public API methods (invariant I6 — see SESSION_CONFIG_COHERENCE_PLAN.md): its ONLY resolution API is Completion::resolve_after, which takes a run future — so resolving a public method’s promise at message-handling time (before the renders it caused have drawn) is unwritable, not merely discouraged. Dropping an unresolved Completion rejects the caller as cancelled.

Implementations

impl Completion

pub fn new() -> (Self, Receiver<ApiResult<()>>)

pub fn resolve_after(self, run: impl Future<Output = ApiResult<()>> + 'static)

Resolve this completion with run’s result when it settles. The caller relinquishes the handle — one run, one resolution.

Trait Implementations

impl Debug for Completion

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

Formats the value using the given formatter.

impl Drop for Completion

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.
