Trait EncodedMessage 

pub trait EncodedMessage {
    // Required methods
    fn code(&self) -> u8;
    fn options_and_payload(&self) -> &[u8];
}

A trait that can implemented on in-memory encoded messages; then, an EncodedMessageView struct can be placed around the implementer to implement coap_message::ReadableMessage.

Implementations must not alter the content returned by the accessors. As this trait is safe to implement, the content of the returned slice could change between calls even when the encoded message was owned or exclusively referenced (e.g. when backed by a RefCell). Therefore, neither this crate nor others can rely on the content upholding any safety guarantees – but it may (and should) panic rater than erring if the expectation of stable content is violated.

Required Methods

fn code(&self) -> u8

The code of the message

fn options_and_payload(&self) -> &[u8]

The memory area containing the encoded options, payload marker and payload

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
