Struct Listener 

pub struct Listener<'a, T: Rpc, S: Service> { /* private fields */ }

Available on crate feature internal-rpc only.

Listens on RPC requests processing them according to a service.

Implementations

impl<'a, T: Rpc, S: Service> Listener<'a, T, S>

pub fn new(rpc: &'a T, service: S) -> Self

Starts listening for RPC requests.

The service argument processes requests. Note that it may be an Fn(request: Vec<u8>) -> Vec<u8> closure, see Service::process() for callback documentation.

The listener stops listening when dropped.

Examples

Listener::new(&platform::protocol::RpcProtocol, |request| Response::from(request))

pub fn stop(self)

Stops listening.

This is equivalent to calling core::mem::drop().

pub fn leak(self)

Drops the listener but continues listening.

This is equivalent to calling core::mem::forget(). This can be useful if the listener is created deeply in the stack but the callback must continue processing RPCs until the applet exits or traps.

Trait Implementations

impl<'a, T: Rpc, S: Service> Drop for Listener<'a, T, S>

fn drop(&mut self)

Executes the destructor for this type.
