Enum PresentationBufferState

enum PresentationBufferState {
    Unassigned,
    Available,
    Mapping,
    Mapped,
}

States of presentation buffer

Variants

Unassigned

Initial state, buffer has yet to be created, only its id is reserved

Available

Buffer is already created and ready to be used immediately

Mapping

Buffer is currently running mapAsync

Mapped

Buffer is currently actively mapped to be used by wr

Trait Implementations

impl Clone for PresentationBufferState

fn clone(&self) -> PresentationBufferState

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PresentationBufferState

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

Formats the value using the given formatter.

impl Default for PresentationBufferState

fn default() -> PresentationBufferState

Returns the “default value” for a type.

impl Ord for PresentationBufferState

fn cmp(&self, other: &PresentationBufferState) -> 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 PresentationBufferState

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

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