Fields

tile: TileId

Tile tracked by this record.

first_selected_frame: Option<u64>

First frame where the tile was selected.

first_queued_frame: Option<u64>

First frame where the tile entered the pending queue.

first_dispatched_frame: Option<u64>

First frame where the tile was dispatched.

first_completed_frame: Option<u64>

First frame where the tile completed.

first_decoded_frame: Option<u64>

First frame where the tile payload passed validation / decode.

first_promoted_frame: Option<u64>

First frame where the tile was promoted to the cache.

first_renderable_frame: Option<u64>

First frame where the tile became renderable in the visible set.

first_exact_frame: Option<u64>

First frame where the tile was used as the exact visible tile.

first_fallback_frame: Option<u64>

First frame where the tile was used as fallback imagery.

queued_frames_to_dispatch: Option<u64>

Frame delta between first queue and first dispatch.

in_flight_frames_to_complete: Option<u64>

Frame delta between first dispatch and first completion.

completion_to_visible_use_frames: Option<u64>

Frame delta between first completion and first visible renderable use.

last_event_frame: u64

Most recent frame where any lifecycle event was recorded.

terminal_event: Option<TileLifecycleEventKind>

Terminal transition, if the record has completed.

Trait Implementations

impl Clone for TileLifecycleRecord

fn clone(&self) -> TileLifecycleRecord

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TileLifecycleRecord

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

Formats the value using the given formatter.

impl Eq for TileLifecycleRecord

impl PartialEq for TileLifecycleRecord

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