Struct netstack3_base::socket::SocketDeviceUpdate

pub struct SocketDeviceUpdate<'a, A: IpAddress, D: WeakDeviceIdentifier> {
    pub local_ip: Option<&'a SpecifiedAddr<A>>,
    pub remote_ip: Option<&'a SpecifiedAddr<A>>,
    pub old_device: Option<&'a D>,
}

A helper type to verify if applying socket updates is allowed for a given current state.

The fields in SocketDeviceUpdate define the current state, [SocketDeviceUpdate::try_update] applies the verification logic.

Fields

local_ip: Option<&'a SpecifiedAddr<A>>

The current local IP address.

remote_ip: Option<&'a SpecifiedAddr<A>>

The current remote IP address.

old_device: Option<&'a D>

The currently bound device.

Implementations

impl<'a, A: IpAddress, D: WeakDeviceIdentifier> SocketDeviceUpdate<'a, A, D>

pub fn check_update<N>( self, new_device: Option<&N>, ) -> Result<(), SocketDeviceUpdateNotAllowedError>

where D: PartialEq<N>,

Checks if an update from old_device to new_device is allowed, returning an error if not.
