Struct Descriptor 

pub struct Descriptor { /* private fields */ }

A Bluetooth GATT descriptor.

Implementations

impl Descriptor

pub fn uuid(&self) -> Uuid

The Uuid identifying the type of this GATT descriptor.

pub async fn uuid_async(&self) -> Result<Uuid>

This method is kept for compatibility with bluest.

pub async fn value(&self) -> Result<Vec<u8>>

The cached value of this descriptor. Returns an error if the value has not yet been read.

pub async fn read(&self) -> Result<Vec<u8>>

Read the value of this descriptor from the device.

pub async fn write(&self, value: &[u8]) -> Result<()>

Write the value to this descriptor on the device.

Trait Implementations

impl Clone for Descriptor

fn clone(&self) -> Descriptor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Descriptor

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

Formats the value using the given formatter.

impl PartialEq for Descriptor

fn eq(&self, other: &Self) -> 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.
