Struct NullLocalEndpoint

pub struct NullLocalEndpoint
where
    Self: Send + Sync;

A dummy endpoint implementation that doesn’t do anything. Useful for testing.

Trait Implementations

impl Debug for NullLocalEndpoint

where Self: Send + Sync,

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

Formats the value using the given formatter.

impl LocalEndpoint for NullLocalEndpoint

type SocketAddr = SocketAddr

The SocketAddr type to use with this local endpoint. This is usually simply std::net::SocketAddr, but may be different in some cases (like for CoAP-SMS endpoints).

type SocketError = Error

The error type associated with errors generated by socket and address-lookup operations. Typically, this is std::io::Error, but it may be different if Self::SocketAddr isn’t std::net::SocketAddr.

type DefaultTransParams = StandardCoapConstants

The trait representing the default transmission parameters to use.

type RemoteEndpoint = NullRemoteEndpoint

The concrete type for a RemoteEndpoint associated with this local endpoint.

type LookupStream = Iter<IntoIter<<NullLocalEndpoint as LocalEndpoint>::SocketAddr>>

The concrete return type of the lookup() method.

type InboundContext = NullInboundContext

Type used by closure that is passed into send(), representing the context for the response.

type RespondableInboundContext = NullRespondableInboundContext

Type used by closure that is passed into receive(), representing the context for inbound requests.

fn scheme(&self) -> &'static str

Returns a string representing the scheme of the underlying transport. For example, this could return "coap", "coaps+sms", etc.

fn default_port(&self) -> u16

Returns the default port to use when the port is unspecified. This value is typically defined by the scheme. Returns zero if port numbers are ignored by the underlying technology.

fn remote_endpoint<S, H, P>( &self, _addr: S, _host: Option<H>, _path: P, ) -> Self::RemoteEndpoint

where S: ToSocketAddrs<SocketAddr = Self::SocketAddr, Error = Self::SocketError>, H: Into<String>, P: Into<RelRefBuf>,

Constructs a new RemoteEndpoint instance for the given address, host, and path.

fn remote_endpoint_from_uri( &self, _uri: &Uri, ) -> Result<Self::RemoteEndpoint, Error>

Constructs a new RemoteEndpoint instance for the given Uri.

fn lookup( &self, _hostname: &str, _port: u16, ) -> Result<Self::LookupStream, Error>

Method for asynchronously looking up the Self::SocketAddr instances for the given hostname and port.

fn send<'a, S, R, SD>( &'a self, _dest: S, _send_desc: SD, ) -> BoxFuture<'a, Result<R, Error>>

where S: ToSocketAddrs<SocketAddr = Self::SocketAddr, Error = Self::SocketError> + 'a, SD: SendDesc<Self::InboundContext, R> + 'a, R: Send + 'a,

Sends a message to remote_addr based on the criteria provided by send_desc.

fn receive<'a, F>(&'a self, _handler: F) -> BoxFuture<'a, Result<(), Error>>

where F: FnMut(&Self::RespondableInboundContext) -> Result<(), Error> + 'a,

Receives a single request and runs the given handler on it once.
