Struct Callback 

pub struct Callback(/* private fields */);

Callback object.

Client-side interface proxy for interface ei_callback.

Interface for ensuring a roundtrip to the EIS implementation. Clients can handle the ‘done’ event to get notified when the related request that created the ei_callback object is done.

Implementations

impl Callback

pub fn version(&self) -> u32

Returns the negotiated version of the interface.

pub fn is_alive(&self) -> bool

Returns true if the backend has this object.

Trait Implementations

impl Clone for Callback

fn clone(&self) -> Callback

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Callback

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

Formats the value using the given formatter.

impl Hash for Callback

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 Interface for Callback

const NAME: &'static str = "ei_callback"

The name of the interface like ei_device.

const VERSION: u32 = 1

The version of the interface this interface proxy supports.

const CLIENT_SIDE: bool = true

Whether this interface proxy is to be used on the client or the server side.

fn new_unchecked(object: Object) -> Self

Returns an interface proxy without checking Object::interface.

fn as_object(&self) -> &Object

Returns a reference to the object contained in the interface proxy.

fn as_arg(&self) -> Arg<'_>

Returns an Arg to reference this object in events or requests.

impl PartialEq for Callback

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