Struct ReadByTypeResult

pub struct ReadByTypeResult {
    pub id: Option<u64>,
    pub value: Option<Vec<u8>>,
    pub error: Option<Error>,
    /* private fields */
}

Fields

id: Option<u64>

Characteristic or descriptor id.

value: Option<Vec<u8>>

Truncated value of characteristic or descriptor, if it was read successfully.

error: Option<Error>

Reason the value could not be read, if reading it resulted in an error.

Trait Implementations

impl Clone for ReadByTypeResult

fn clone(&self) -> ReadByTypeResult

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ReadByTypeResult

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

Formats the value using the given formatter.

impl<D> Decode<ReadByTypeResult, D> for ReadByTypeResult

where D: ResourceDialect,

fn new_empty() -> ReadByTypeResult

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 Default for ReadByTypeResult

fn default() -> ReadByTypeResult

Returns the “default value” for a type.

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

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 PartialEq for ReadByTypeResult

fn eq(&self, other: &ReadByTypeResult) -> 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 TypeMarker for ReadByTypeResult

type Owned = ReadByTypeResult

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 ReadByTypeResult

type Borrowed<'a> = &'a ReadByTypeResult

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: &<ReadByTypeResult as TypeMarker>::Owned, ) -> <ReadByTypeResult as ValueTypeMarker>::Borrowed<'_>

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