Struct ResultType

pub struct ResultType<T: TypeMarker, E: TypeMarker>(/* private fields */);

The FIDL union generated for strict two-way methods with errors.

Trait Implementations

impl<D: ResourceDialect, T: TypeMarker, E: TypeMarker> Decode<ResultType<T, E>, D> for Result<T::Owned, E::Owned>

where T::Owned: Decode<T, D>, E::Owned: Decode<E, 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<D: ResourceDialect, T: TypeMarker, X: Encode<T, D>, E: TypeMarker, Y: Encode<E, D>> Encode<ResultType<T, E>, D> for Result<X, Y>

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: TypeMarker, E: TypeMarker> TypeMarker for ResultType<T, E>

type Owned = Result<<T as TypeMarker>::Owned, <E as TypeMarker>::Owned>

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.
