Enum FrameDropReason

#[repr(i32)]
pub enum FrameDropReason {
    ReasonUnspecified = 0,
    ReasonDisplayCompositor = 1,
    ReasonMainThread = 2,
    ReasonClientCompositor = 3,
}

Variants

ReasonUnspecified = 0

ReasonDisplayCompositor = 1

Frame was dropped by the display-compositor. The display-compositor may drop a frame some times (e.g. the frame missed the deadline, or was blocked on surface-sync, etc.)

ReasonMainThread = 2

Frame was dropped because of the main-thread. The main-thread may cause a frame to be dropped, e.g. if the main-thread is running expensive javascript, or doing a lot of layout updates, etc.

ReasonClientCompositor = 3

Frame was dropped by the client compositor. The client compositor can drop some frames too (e.g. attempting to recover latency, missing the deadline, etc.).

Implementations

impl FrameDropReason

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of FrameDropReason.

pub fn from_i32(value: i32) -> Option<FrameDropReason>

Converts an i32 to a FrameDropReason, or None if value is not a valid variant.

impl FrameDropReason

pub fn as_str_name(&self) -> &'static str

String value of the enum field names used in the ProtoBuf definition.

The values are not transformed in any way and thus are considered stable (if the ProtoBuf definition does not change) and safe for programmatic use.

Trait Implementations

impl Clone for FrameDropReason

fn clone(&self) -> FrameDropReason

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FrameDropReason

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

Formats the value using the given formatter.

impl Default for FrameDropReason

fn default() -> FrameDropReason

Returns the “default value” for a type.

impl From<FrameDropReason> for i32

fn from(value: FrameDropReason) -> i32

Converts to this type from the input type.

impl Hash for FrameDropReason

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 Ord for FrameDropReason

fn cmp(&self, other: &FrameDropReason) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for FrameDropReason

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

impl PartialOrd for FrameDropReason

fn partial_cmp(&self, other: &FrameDropReason) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
