Struct capsules_extra::net::sixlowpan::sixlowpan_state::Sixlowpan

pub struct Sixlowpan<'a, A: Alarm<'a>, C: ContextStore> {
    pub ctx_store: C,
    /* private fields */
}

Sends a receives IPv6 packets via 6loWPAN compression and fragmentation.

Initialization

The new method creates an instance of Sixlowpan that can send packets. To receive packets, Sixlowpan needs one or more RxStates which can be added with add_rx_state. More RxStates allow the Sixlowpan to receive more packets concurrently.

Finally, set_client controls the client that will receive transmission completion and reception callbacks.

Fields

ctx_store: C

Implementations

impl<'a, A: Alarm<'a>, C: ContextStore> Sixlowpan<'a, A, C>

pub fn new(ctx_store: C, clock: &'a A) -> Sixlowpan<'a, A, C>

Creates a new Sixlowpan

Arguments

• ctx_store - Stores IPv6 address nextwork context mappings

• tx_buf - A buffer used for storing individual fragments of a packet in transmission. This buffer must be at least the length of an 802.15.4 frame.

• clock - A implementation of Alarm used for tracking the timing of frame arrival. The clock should be continue running during sleep and have an accuracy of at least 60 seconds.

Trait Implementations

impl<'a, A: Alarm<'a>, C: ContextStore> RxClient for Sixlowpan<'a, A, C>

fn receive<'b>( &self, buf: &'b [u8], header: Header<'b>, _lqi: u8, data_offset: usize, data_len: usize, )

When a frame is received, this callback is triggered. The client only receives an immutable borrow of the buffer. Only completely valid, unsecured frames that have passed the incoming security procedure are exposed to the client.

impl<'a, A: Alarm<'a>, C: ContextStore> SixlowpanState<'a> for Sixlowpan<'a, A, C>

fn add_rx_state(&self, rx_state: &'a RxState<'a>)

Adds an additional RxState for reassembling IPv6 packets

Each RxState struct allows an additional IPv6 packet to be reassembled concurrently.

fn set_rx_client(&'a self, client: &'a dyn SixlowpanRxClient)

Sets the SixlowpanClient that will receive transmission completion and new packet reception callbacks.
