Struct WriteOptions 

pub struct WriteOptions {
    pub write_mode: Option<WriteMode>,
    pub offset: Option<u16>,
    /* private fields */
}

Represents the supported options to write a characteristic/descriptor value to a server.

Fields

write_mode: Option<WriteMode>

The mode of the write operation. For descriptors, only [WriteMode.DEFAULT] is supported Optional. Default: [WriteMode.DEFAULT]

offset: Option<u16>

Request a write starting at the byte indicated. Must be missing or 0 if write_mode is [WriteMode.WITHOUT_RESPONSE]. Optional. Default: 0

Trait Implementations

impl Clone for WriteOptions

fn clone(&self) -> WriteOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WriteOptions

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

Formats the value using the given formatter.

impl<D> Decode<WriteOptions, D> for WriteOptions

where D: ResourceDialect,

fn new_empty() -> WriteOptions

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 WriteOptions

fn default() -> WriteOptions

Returns the “default value” for a type.

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

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 WriteOptions

fn eq(&self, other: &WriteOptions) -> 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 WriteOptions

type Owned = WriteOptions

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 WriteOptions

type Borrowed<'a> = &'a WriteOptions

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

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