LoWPAN encoding requires being able to look up the existence of contexts, which are essentially IPv6 address prefixes. Any implementation must ensure that context 0 is always available and contains the mesh-local prefix.

Required Methods

fn get_context_from_addr(&self, ip_addr: IPAddr) -> Option<Context>

fn get_context_from_id(&self, ctx_id: u8) -> Option<Context>

fn get_context_from_prefix( &self, prefix: &[u8], prefix_len: u8, ) -> Option<Context>

Provided Methods

fn get_context_0(&self) -> Context

Implementors

impl ContextStore for Context
