BoxBuffer

coap_message_implementations::inmemory

Struct BoxBuffer 

Source 
pub struct BoxBuffer { /* private fields */ }
Available on crate feature alloc only.
Expand description

An owned (heap allocated) CoAP message buffer.

This is mostly practical for testing to have something similar to SliceBuffer / SliceBufferMut that is distinct from them, and shows how the MessageBuffer/…Mut traits generalize over ownership.

Implementations§
