Fields

command: LifecycleCommand

Lifecycle command being issued.

Trigger

A scheduled or event-driven trigger.

Fields

source: Symbol

Symbol naming the trigger source.

Implementations

impl FrameKind

pub fn as_symbol(&self) -> Symbol

Returns the symbol naming this frame kind (e.g. request, stream-end).

Trait Implementations

impl Clone for FrameKind

fn clone(&self) -> FrameKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FrameKind

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

Formats the value using the given formatter.

impl Eq for FrameKind

impl PartialEq for FrameKind

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