Struct fidl::encoding::Array

pub struct Array<T: TypeMarker, const N: usize>(/* private fields */);

The FIDL type array<T, N>.

Trait Implementations

impl<T: TypeMarker, const N: usize, D: ResourceDialect> Decode<Array<T, N>, D> for [T::Owned; N]

where T::Owned: Decode<T, D>,

fn new_empty() -> Self

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<()>

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

impl<T: ValueTypeMarker, const N: usize, D: ResourceDialect> Encode<Array<T, N>, D> for &[T::Owned; N]

where for<'q> T::Borrowed<'q>: Encode<T, D>,

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

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

impl<T: ResourceTypeMarker, const N: usize, D: ResourceDialect> Encode<Array<T, N>, D> for &mut [<T as TypeMarker>::Owned; N]

where for<'q> T::Borrowed<'q>: Encode<T, D>,

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

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

impl<T: ResourceTypeMarker, const N: usize> ResourceTypeMarker for Array<T, N>

type Borrowed<'a> = &'a mut [<T as TypeMarker>::Owned; N]

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

fn take_or_borrow(value: &mut <Self as TypeMarker>::Owned) -> Self::Borrowed<'_>

Cheaply converts from &mut Self::Owned to Self::Borrowed. For HandleBased types this is “take” (it returns an owned handle and replaces value with Handle::invalid), and for all other types it is “borrow” (just converts from one reference to another).

impl<T: TypeMarker, const N: usize> TypeMarker for Array<T, N>

type Owned = [<T as TypeMarker>::Owned; N]

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<T: ValueTypeMarker, const N: usize> ValueTypeMarker for Array<T, N>

type Borrowed<'a> = &'a [<T as TypeMarker>::Owned; N]

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: &Self::Owned) -> Self::Borrowed<'_>

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