Struct GenericMessageType

pub struct GenericMessageType<H: ValueTypeMarker, T: TypeMarker>(/* private fields */);

The FIDL type for a message consisting of a header H and body T.

Trait Implementations

impl<H: ValueTypeMarker, T: TypeMarker, D: ResourceDialect> Decode<GenericMessageType<H, T>, D> for GenericMessageOwned

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<H: ValueTypeMarker, T: TypeMarker, E: Encode<T, D>, D: ResourceDialect> Encode<GenericMessageType<H, T>, D> for GenericMessage<<H as TypeMarker>::Owned, E>

where for<'a> H::Borrowed<'a>: Encode<H, 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<H: ValueTypeMarker, T: TypeMarker> TypeMarker for GenericMessageType<H, T>

type Owned = GenericMessageOwned

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.
