Struct LongReadOptions

pub struct LongReadOptions {
    pub offset: Option<u16>,
    pub max_bytes: Option<u16>,
    /* private fields */
}

Represents the supported options to read a long characteristic or descriptor value from a server. Long values are those that may not fit in a single message (longer than 22 bytes).

Fields

offset: Option<u16>

The byte to start the read at. Must be less than the length of the value. Optional. Default: 0

max_bytes: Option<u16>

The maximum number of bytes to read. Optional. Default: MAX_VALUE_LENGTH

Trait Implementations

impl Clone for LongReadOptions

fn clone(&self) -> LongReadOptions

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LongReadOptions

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

Formats the value using the given formatter.

impl<D: ResourceDialect> Decode<LongReadOptions, D> for LongReadOptions

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 Default for LongReadOptions

fn default() -> LongReadOptions

Returns the “default value” for a type.

impl<D: ResourceDialect> Encode<LongReadOptions, D> for &LongReadOptions

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 PartialEq for LongReadOptions

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

type Owned = LongReadOptions

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 LongReadOptions

type Borrowed<'a> = &'a LongReadOptions

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: &<Self as TypeMarker>::Owned) -> Self::Borrowed<'_>

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