Struct ValueChangedParameters

pub struct ValueChangedParameters {
    pub handle: Option<Handle>,
    pub value: Option<Vec<u8>>,
    pub peer_ids: Option<Vec<PeerId>>,
    /* private fields */
}

The parameters used to signal a characteristic value change from a LocalService to a peer.

Fields

handle: Option<Handle>

The handle of the characteristic value being signalled. Mandatory.

value: Option<Vec<u8>>

The updated value of the characteristic. Note for clients using indications/notifications for high-throughput (not recommended): While statically constrained to MAX_VALUE_LENGTH, the real limit depends on the specific peer’s configuration as notified by LocalService.PeerUpdate. Any bytes exceeding that limit are truncated internally by the stack. Mandatory.

peer_ids: Option<Vec<PeerId>>

Only signal a subset of peers. If not present or empty, all peers that can be updated are signaled. If included, only the set of peers in this list will be signaled. Peers are only signaled if they have configured updates or notifications per LocalService. CharacteristicConfiguration; other peers in peer_ids will be ignored.

Trait Implementations

impl Clone for ValueChangedParameters

fn clone(&self) -> ValueChangedParameters

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ValueChangedParameters

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

Formats the value using the given formatter.

impl<D> Decode<ValueChangedParameters, D> for ValueChangedParameters

where D: ResourceDialect,

fn new_empty() -> ValueChangedParameters

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 ValueChangedParameters

fn default() -> ValueChangedParameters

Returns the “default value” for a type.

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

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 ValueChangedParameters

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

type Owned = ValueChangedParameters

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 ValueChangedParameters

type Borrowed<'a> = &'a ValueChangedParameters

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

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