Enum wayland_protocols::wp::tearing_control::v1::server::wp_tearing_control_v1::PresentationHint

#[non_exhaustive]
#[repr(u32)]
pub enum PresentationHint {
    Vsync = 0,
    Async = 1,
}

presentation hint values

This enum provides information for if submitted frames from the client may be presented with tearing.

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.

Vsync = 0

tearing-free presentation

The content of this surface is meant to be synchronized to the vertical blanking period. This should not result in visible tearing and may result in a delay before a surface commit is presented.

Async = 1

asynchronous presentation

The content of this surface is meant to be presented with minimal latency and tearing is acceptable.

Trait Implementations

impl Clone for PresentationHint

fn clone(&self) -> PresentationHint

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PresentationHint

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

Formats the value using the given formatter.

impl From<PresentationHint> for u32

fn from(val: PresentationHint) -> u32

Converts to this type from the input type.

impl Hash for PresentationHint

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 PresentationHint

fn cmp(&self, other: &PresentationHint) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for PresentationHint

fn eq(&self, other: &PresentationHint) -> 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 PresentationHint

fn partial_cmp(&self, other: &PresentationHint) -> 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.

impl TryFrom<u32> for PresentationHint

type Error = ()

The type returned in the event of a conversion error.

fn try_from(val: u32) -> Result<PresentationHint, ()>

Performs the conversion.
