Struct nat_traversal::MappingContext

pub struct MappingContext {
    // some fields omitted
}

You need to create a MappingContext before doing any socket mapping. This MappingContext should ideally be kept throughout the lifetime of the program. Internally it caches a addresses of UPnP servers and hole punching servers.

Methods

impl MappingContext

fn new() -> WResult<MappingContext, MappingContextNewWarning, MappingContextNewError>

Create a new mapping context. This will block breifly while it searches the network for UPnP servers.

fn add_simple_udp_servers<S>(&self, servers: S) where S: IntoIterator<Item=SocketAddr>

Inform the context about external servers that speak the UDP simple hole punch server protocol.

fn add_simple_tcp_servers<S>(&self, servers: S) where S: IntoIterator<Item=SocketAddr>

Inform the context about external servers that speak the TCP simple hole punch server protocol.
