Struct FormatCostKey 

pub struct FormatCostKey {
    pub pixel_format: Option<PixelFormat>,
    pub pixel_format_modifier: Option<PixelFormatModifier>,
    pub buffer_usage_bits: Option<BufferUsage>,
}

Entries which have the same pixel_format, pixel_format_modifier, and required_usage_bits as a previous entry will override that previous entry. For matching purposes, an absent pixel_format_modifier matches LINEAR, and an absent required_buffer_usage_bits matches all-0 usage bits.

Fields

pixel_format: Option<PixelFormat>

pixel_format_modifier: Option<PixelFormatModifier>

buffer_usage_bits: Option<BufferUsage>

Trait Implementations

impl Clone for FormatCostKey

fn clone(&self) -> FormatCostKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FormatCostKey

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

Formats the value using the given formatter.

impl Default for FormatCostKey

fn default() -> FormatCostKey

Returns the “default value” for a type.

impl<'a, ___E> Encode<FormatCostKey<'static>, ___E> for &'a FormatCostKey

where ___E: Encoder + ?Sized,

fn encode( self, encoder: &mut ___E, out: &mut MaybeUninit<FormatCostKey<'static>>, _: (), ) -> Result<(), EncodeError>

Encodes this value into an encoder and output.

const COPY_OPTIMIZATION: CopyOptimization<Self, W> = _

Whether the conversion from Self to W is equivalent to copying the raw bytes of Self.

impl<___E> Encode<FormatCostKey<'static>, ___E> for FormatCostKey

where ___E: Encoder + ?Sized,

fn encode( self, encoder: &mut ___E, out: &mut MaybeUninit<FormatCostKey<'static>>, _: (), ) -> Result<(), EncodeError>

Encodes this value into an encoder and output.

const COPY_OPTIMIZATION: CopyOptimization<Self, W> = _

Whether the conversion from Self to W is equivalent to copying the raw bytes of Self.

impl<'de> FromWire<FormatCostKey<'de>> for FormatCostKey

fn from_wire(wire_: FormatCostKey<'de>) -> Self

Converts the given owned value to this type.

const COPY_OPTIMIZATION: CopyOptimization<W, Self> = _

Whether the conversion from W to Self is equivalent to copying the raw bytes of W.

impl<'de> FromWireRef<FormatCostKey<'de>> for FormatCostKey

fn from_wire_ref(wire: &FormatCostKey<'de>) -> Self

Converts the given reference to this type.

impl Hash for FormatCostKey

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 FormatCostKey

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

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

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