Struct BufferCollectionConstraintsAuxBuffers

pub struct BufferCollectionConstraintsAuxBuffers {
    pub need_clear_aux_buffers_for_secure: bool,
    pub allow_clear_aux_buffers_for_secure: bool,
}

Fields

need_clear_aux_buffers_for_secure: bool

If true, a secure heap may only be selected if all participants with BufferMemoryConstraints specify allow_clear_aux_buffers_for_secure. If “need” is true, “allow” must also be true.

If false, the participant can still work, potentially even with secure memory (depending on supported heaps), without clear aux buffers.

allow_clear_aux_buffers_for_secure: bool

If true, the participant will use clear aux buffers, if they are allocated, as appropriate to the participant’s role. If the participant is a producer, then the participant producer will populate the clear aux buffers with the clear (not-encrypted, not-DRM-protected) bytes, and fill protected bytes with data that does not emulate start codes, such as 0xFF.

If BufferCollectionConstraintsAuxBuffers is never sent by a participant, then “allow” is true iff the participant specifies usage which is read only.

If unspecified by a participant with write usage, or false, the buffer collection won’t be able to allocate if any participant specifies need_clear_aux_buffers_for_secure true.

Trait Implementations

impl Clone for BufferCollectionConstraintsAuxBuffers

fn clone(&self) -> BufferCollectionConstraintsAuxBuffers

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BufferCollectionConstraintsAuxBuffers

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

Formats the value using the given formatter.

impl<D> Decode<BufferCollectionConstraintsAuxBuffers, D> for BufferCollectionConstraintsAuxBuffers

where D: ResourceDialect,

fn new_empty() -> BufferCollectionConstraintsAuxBuffers

Creates a valid instance of Self. The specific value does not matter, since it will be overwritten by decode.

unsafe fn decode( &mut self, decoder: &mut Decoder<'_, D>, offset: usize, _depth: Depth, ) -> Result<(), Error>

Decodes an object of type T from the decoder’s buffers into self.

impl<D> Encode<BufferCollectionConstraintsAuxBuffers, D> for &BufferCollectionConstraintsAuxBuffers

where D: ResourceDialect,

unsafe fn encode( self, encoder: &mut Encoder<'_, D>, offset: usize, _depth: Depth, ) -> Result<(), Error>

Encodes the object into the encoder’s buffers. Any handles stored in the object are swapped for Handle::INVALID.

impl Hash for BufferCollectionConstraintsAuxBuffers

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 BufferCollectionConstraintsAuxBuffers

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

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

fn partial_cmp( &self, other: &BufferCollectionConstraintsAuxBuffers, ) -> 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 TypeMarker for BufferCollectionConstraintsAuxBuffers

type Owned = BufferCollectionConstraintsAuxBuffers

The owned Rust type which this FIDL type decodes into.

fn inline_align(_context: Context) -> usize

Returns the minimum required alignment of the inline portion of the encoded object. It must be a (nonzero) power of two.

fn inline_size(_context: Context) -> usize

Returns the size of the inline portion of the encoded object, including padding for alignment. Must be a multiple of inline_align.

fn encode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and encoding requires no validation. When true, we can optimize encoding arrays and vectors of Self::Owned to a single memcpy.

fn decode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and decoding requires no validation. When true, we can optimize decoding arrays and vectors of Self::Owned to a single memcpy.

impl ValueTypeMarker for BufferCollectionConstraintsAuxBuffers

type Borrowed<'a> = &'a BufferCollectionConstraintsAuxBuffers

The Rust type to use for encoding. This is a particular Encode<Self> type cheaply obtainable from &Self::Owned. There are three cases:

fn borrow( value: &<BufferCollectionConstraintsAuxBuffers as TypeMarker>::Owned, ) -> <BufferCollectionConstraintsAuxBuffers as ValueTypeMarker>::Borrowed<'_>

Cheaply converts from &Self::Owned to Self::Borrowed.
