}

Constraints on allocated buffers and, optionally, constraints on images stored in the buffers. These constraints can be specified per-participant. The sysmem service implements aggregation of constraints from multiple participants.

Trait Implementations

impl Clone for BufferCollectionConstraints

fn clone(&self) -> BufferCollectionConstraints

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BufferCollectionConstraints

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

Formats the value using the given formatter.

impl Default for BufferCollectionConstraints

fn default() -> BufferCollectionConstraints

Returns the “default value” for a type.

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

where ___E: Encoder + ?Sized,

fn encode( self, encoder: &mut ___E, out: &mut MaybeUninit<BufferCollectionConstraints<'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<BufferCollectionConstraints<'static>, ___E> for BufferCollectionConstraints

where ___E: Encoder + ?Sized,

fn encode( self, encoder: &mut ___E, out: &mut MaybeUninit<BufferCollectionConstraints<'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<BufferCollectionConstraints<'de>> for BufferCollectionConstraints

fn from_wire( wire_: BufferCollectionConstraints<'de>, ) -> BufferCollectionConstraints

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<BufferCollectionConstraints<'de>> for BufferCollectionConstraints

fn from_wire_ref( wire: &BufferCollectionConstraints<'de>, ) -> BufferCollectionConstraints

Converts the given reference to this type.

impl PartialEq for BufferCollectionConstraints

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