Enum StartCause

pub enum StartCause {
    ResumeTimeReached {
        start: Instant,
        requested_resume: Instant,
    },
    WaitCancelled {
        start: Instant,
        requested_resume: Option<Instant>,
    },
    Poll,
    Init,
}

Describes the reason the event loop is resuming.

Variants

ResumeTimeReached

Sent if the time specified by ControlFlow::WaitUntil has been reached. Contains the moment the timeout was requested and the requested resume time. The actual resume time is guaranteed to be equal to or after the requested resume time.

Fields

start: Instant

requested_resume: Instant

WaitCancelled

Sent if the OS has new events to send to the window, after a wait was requested. Contains the moment the wait was requested and the resume time, if requested.

Fields

start: Instant

requested_resume: Option<Instant>

Poll

Sent if the event loop is being resumed after the loop’s control flow was set to ControlFlow::Poll.

Init

Sent once, immediately after run is called. Indicates that the loop was just initialized.

Trait Implementations

impl Clone for StartCause

fn clone(&self) -> StartCause

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StartCause

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

Formats the value using the given formatter.

impl Hash for StartCause

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for StartCause

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