}Expand description
A type which allows querying a remote FIDL server over a channel, blocking the calling thread.
Required Associated Types§
Sourcetype Protocol: ProtocolMarker<Proxy = Self::Proxy>
type Protocol: ProtocolMarker<Proxy = Self::Proxy>
The protocol which this Proxy controls.
Required Methods§
Sourcefn from_channel(inner: Channel) -> Self
fn from_channel(inner: Channel) -> Self
Create a proxy over the given channel.
Sourcefn into_channel(self) -> Channel
fn into_channel(self) -> Channel
Convert the proxy back into a channel.
Sourcefn as_channel(&self) -> &Channel
fn as_channel(&self) -> &Channel
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§
Sourcefn is_closed(&self) -> Result<bool, Status>
fn is_closed(&self) -> Result<bool, Status>
Returns true if the proxy has received the PEER_CLOSED signal.
§Errors
See https://fuchsia.dev/reference/syscalls/object_wait_one?hl=en#errors for a full list of
errors. Note that Status::TIMED_OUT errors are converted to Ok(false) and all other
errors are propagated.
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
