Struct Characteristic 

pub struct Characteristic {
    pub handle: Option<Handle>,
    pub type_: Option<Uuid>,
    pub properties: Option<CharacteristicPropertyBits>,
    pub permissions: Option<AttributePermissions>,
    pub descriptors: Option<Vec<Descriptor>>,
    /* private fields */
}

Represents a local or remote GATT characteristic.

Fields

handle: Option<Handle>

Uniquely identifies this characteristic within a service. For local characteristics, the specified handle must be unique across all characteristic and descriptor handles in this service.

Always present. For local characteristics, this value is mandatory.

type_: Option<Uuid>

The UUID that identifies the type of this characteristic. Always present. Mandatory for local characteristics.

properties: Option<CharacteristicPropertyBits>

The characteristic properties bitfield. Always present. Mandatory for local characteristics.

permissions: Option<AttributePermissions>

The attribute permissions of this characteristic. For remote characteristics, this value will not be present until the permissions are discovered via read and write requests.

For local characteristics, this value is mandatory.

descriptors: Option<Vec<Descriptor>>

The descriptors of this characteristic. Present only if non-empty. Optional for local characteristics.

Trait Implementations

impl Clone for Characteristic

fn clone(&self) -> Characteristic

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Characteristic

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

Formats the value using the given formatter.

impl<D> Decode<Characteristic, D> for Characteristic

where D: ResourceDialect,

fn new_empty() -> Characteristic

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 Characteristic

fn default() -> Characteristic

Returns the “default value” for a type.

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

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 Characteristic

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

type Owned = Characteristic

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 Characteristic

type Borrowed<'a> = &'a Characteristic

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

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