Struct coap_message_utils::inmemory::EncodedMessageView

pub struct EncodedMessageView<EM: EncodedMessage> { /* private fields */ }

A wrapper around any data structure containing a readable message

This is not Sync – while it is currently a zero-sized wrapper, it may gain optimizations later such as memoizing where the payload begins (and this is only practical with interior mutability).

See Message for how this does not perform early validation and handles message errors.

Trait Implementations

impl<EM: EncodedMessage> AsRef<EM> for EncodedMessageView<EM>

When the inner item stores more than just the code and encoded options, this can be used to gain read-only access to any additional data. (Mutating access is blocked to ensure that future optimizations like memoizing the payload position are possible; it might still be enabled if memoized data is cleared just to be on the safe side).

fn as_ref(&self) -> &EM

Converts this type into a shared reference of the (usually inferred) input type.

impl<EM: Clone + EncodedMessage> Clone for EncodedMessageView<EM>

fn clone(&self) -> EncodedMessageView<EM>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<EM: Debug + EncodedMessage> Debug for EncodedMessageView<EM>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
