Enum wry::application::event::StartCause

#[non_exhaustive]
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 (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

ResumeTimeReached

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

start: Instant

requested_resume: Instant

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.

WaitCancelled

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

start: Instant

requested_resume: Option<Instant>

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.

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.
