Enum ScreenshotRequestState 

enum ScreenshotRequestState {
    Pending,
    WaitingOnScript,
}

When a ScreenshotReadinessRequest is received from the renderer, the Constellation go through a variety of states to process them. This data structure represents those states.

Variants

Pending

The Constellation has received the ScreenshotReadinessRequest, but has not yet forwarded it to the Pipeline’s of the requests’s WebView. This is likely because there are still pending navigation changes in the Constellation. Once those changes are resolved the request will be forwarded to the Pipelines.

WaitingOnScript

The Constellation has forwarded the ScreenshotReadinessRequest to the Pipelines of the corresponding WebView. The Pipelines are waiting for a variety of things to happen in order to report what appropriate display list epoch is for the screenshot. Once they all report back, the Constellation considers that the request is handled, and the renderer is responsible for waiting to take the screenshot.

Trait Implementations

impl Clone for ScreenshotRequestState

fn clone(&self) -> ScreenshotRequestState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for ScreenshotRequestState

fn default() -> ScreenshotRequestState

Returns the “default value” for a type.

impl PartialEq for ScreenshotRequestState

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