Struct Handle

pub struct Handle(pub u64);

Handles are used as local-to-your-code identifiers for Characteristics and Descriptors.

Their value should be treated as opaque by clients of PeerService, and are explicitly not guaranteed to be equal to a peer’s attribute handles. Stack implementations should provide unique handles for each Characteristic and Descriptor within a PeerService for the client. It is not necessary or expected for different clients of the same service to have the same handles.

For LocalService publishing, Service Definitions are required to have no duplicate Handles across their defined Characteristics and Descriptors. Characteristic and ServiceDefinition will check and return Error::DuplicateHandle. Handles in ServiceDefinitions should not match the attribute handles in the local GATT server. They are local to your code for use in correlating with ServiceEvents from peers. Stacks must translate the actual GATT handles to the handles provided in the ServiceDefinition for these events.

Trait Implementations

impl Clone for Handle

fn clone(&self) -> Handle

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Handle

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

Formats the value using the given formatter.

impl Hash for Handle

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Handle

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