An execution context for the UDP protocol which also provides access to state.

Required Associated Types

type IpSocketsCtx<'a>: TransportIpContext<I, BC> + MulticastMembershipHandler<I, BC> + DeviceIdContext<AnyDevice, DeviceId = Self::DeviceId, WeakDeviceId = Self::WeakDeviceId>

The core context passed to the callback provided to methods.

type DualStackContext: DualStackDatagramBoundStateContext<I, BC, Udp<BC>, DeviceId = Self::DeviceId, WeakDeviceId = Self::WeakDeviceId>

The inner dual stack context.

type NonDualStackContext: NonDualStackDatagramBoundStateContext<I, BC, Udp<BC>, DeviceId = Self::DeviceId, WeakDeviceId = Self::WeakDeviceId>

The inner non dual stack context.

Required Methods

fn with_bound_sockets<O, F: FnOnce(&mut Self::IpSocketsCtx<'_>, &BoundSockets<I, Self::WeakDeviceId, BC>) -> O>( &mut self, cb: F, ) -> O

Calls the function with an immutable reference to UDP sockets.

fn with_bound_sockets_mut<O, F: FnOnce(&mut Self::IpSocketsCtx<'_>, &mut BoundSockets<I, Self::WeakDeviceId, BC>) -> O>( &mut self, cb: F, ) -> O

Calls the function with a mutable reference to UDP sockets.

fn dual_stack_context( &mut self, ) -> MaybeDualStack<&mut Self::DualStackContext, &mut Self::NonDualStackContext>

Returns a context for dual- or non-dual-stack operation.

fn with_transport_context<O, F: FnOnce(&mut Self::IpSocketsCtx<'_>) -> O>( &mut self, cb: F, ) -> O

Calls the function without access to the UDP bound socket state.

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.
