Struct Stack

pub struct Stack<const UDPCOUNT: usize> {
    udp_sockets: Vec<sock_udp_t, UDPCOUNT>,
}

Available on riot_module_sock_udp and crate feature with_embedded_nal only.

The operating system’s network stack, used to get an implementation of embedded_nal::UdpClientStack.

Using this is not trivial, as RIOT needs its sockets pinned to memory for their lifetime. Without a heap allocator, this is achieved by allocating all the required UDP sockets in a stack object. To ensure that it is not moved, sockets on it can only be created in (and live only for the duration of) a the run callback, which gives the actual implementation of UdpClientStack.

The number of UDP sockets allocated is configurable using the UDPCOUNT const generic.

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
