Struct OpResult

pub struct OpResult {
    pub return_code: Option<u64>,
    pub return_origin: Option<ReturnOrigin>,
    pub parameter_set: Option<Vec<Parameter>>,
    /* private fields */
}

The result of an operation will include a return code, the origin of the result, and the return of the parameter set. The returned parameter set will be a copy of the input parameter set, but with the INOUT and OUTPUT parameters updated. If the parameter is a Buffer, it will update the Buffer.size to the number of bytes written.

Fields

return_code: Option<u64>

return_origin: Option<ReturnOrigin>

parameter_set: Option<Vec<Parameter>>

Trait Implementations

impl Debug for OpResult

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

Formats the value using the given formatter.

impl Decode<OpResult, DefaultFuchsiaResourceDialect> for OpResult

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<'_, DefaultFuchsiaResourceDialect>, offset: usize, depth: Depth, ) -> Result<()>

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

impl Default for OpResult

fn default() -> OpResult

Returns the “default value” for a type.

impl Encode<OpResult, DefaultFuchsiaResourceDialect> for &mut OpResult

unsafe fn encode( self, encoder: &mut Encoder<'_, DefaultFuchsiaResourceDialect>, 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 PartialEq for OpResult

fn eq(&self, other: &OpResult) -> 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 ResourceTypeMarker for OpResult

type Borrowed<'a> = &'a mut OpResult

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<'a>( value: &'a mut <Self as TypeMarker>::Owned, ) -> Self::Borrowed<'a>

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 TypeMarker for OpResult

type Owned = OpResult

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.
