Describes Chrome’s Compositor scheduler’s current state and associated variables.

These protos and enums were adapted from the corresponding original JSON trace event for the scheduler state. In contrast to the JSON, we use strongly typed enum values instead of strings for many fields, and microsecond-granularity timestamps.

The original format was generated in JSON by the code at https://cs.chromium.org/chromium/src/cc/scheduler/scheduler.cc?l=870&rcl=5e15eabc9c0eec8daf94fdf78e93f13b6e3b63dd

And is now generated as protozero: https://cs.chromium.org/chromium/src/cc/scheduler/scheduler.cc?q=Scheduler::AsPro

All non-delta-timestamps are absolute CLOCK_MONOTONIC timestamps.

Implementations

impl ChromeCompositorSchedulerAction

pub const fn is_valid(value: i32) -> bool

Returns true if value is a variant of ChromeCompositorSchedulerAction.

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

👎Deprecated:

Use the TryFrom<i32> implementation instead

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

impl ChromeCompositorSchedulerAction

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.

pub fn from_str_name(value: &str) -> Option<Self>

Creates an enum from field names used in the ProtoBuf definition.

Trait Implementations

impl Clone for ChromeCompositorSchedulerAction

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ChromeCompositorSchedulerAction

impl Debug for ChromeCompositorSchedulerAction

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

Formats the value using the given formatter.

impl Default for ChromeCompositorSchedulerAction

fn default() -> ChromeCompositorSchedulerAction

Returns the “default value” for a type.

impl Eq for ChromeCompositorSchedulerAction

impl From<ChromeCompositorSchedulerAction> for i32

fn from(value: ChromeCompositorSchedulerAction) -> i32

Converts to this type from the input type.

impl Hash for ChromeCompositorSchedulerAction

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 ChromeCompositorSchedulerAction

fn cmp(&self, other: &Self) -> 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.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for ChromeCompositorSchedulerAction

fn eq(&self, other: &Self) -> bool

Equality operator ==.

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

impl PartialOrd for ChromeCompositorSchedulerAction

fn partial_cmp(&self, other: &Self) -> 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

impl StructuralPartialEq for ChromeCompositorSchedulerAction

impl TryFrom<i32> for ChromeCompositorSchedulerAction

type Error = UnknownEnumValue

The type returned in the event of a conversion error.

fn try_from( value: i32, ) -> Result<ChromeCompositorSchedulerAction, UnknownEnumValue>

Performs the conversion.
