Expand description

A type which allows querying a remote FIDL server over a channel.

Required Associated Types§


type Protocol: ProtocolMarker<Proxy = Self>

The protocol which this Proxy controls.

Required Methods§


fn from_channel(inner: AsyncChannel) -> Self

Create a proxy over the given channel.


fn into_channel(self) -> Result<AsyncChannel, Self>

Attempt to convert the proxy back into a channel.

This will only succeed if there are no active clones of this proxy and no currently-alive EventStream or response futures that came from this proxy.


fn as_channel(&self) -> &AsyncChannel

Get a reference to the proxy’s underlying channel.

This should only be used for non-effectful operations. Reading or writing to the channel is unsafe because the proxy assumes it has exclusive control over these operations.

Provided Methods§


fn is_closed(&self) -> bool

Returns true if the proxy has received the PEER_CLOSED signal.


fn on_closed<'a>(&'a self) -> OnSignals<'a>

Returns a future that completes when the proxy receives the PEER_CLOSED signal.
