Required methods

fn msg_code(&self) -> MsgCode

Gets the message code for this message.

fn msg_type(&self) -> MsgType

Gets the message type for this message.

fn msg_id(&self) -> MsgId

Gets the message id for this message.

fn msg_token(&self) -> MsgToken

Gets the message token for this message.

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

ⓘImportant traits for OptionIterator<'a>
fn options(&self) -> OptionIterator

Gets an iterator for processing the options of the message.

fn content_format(&self) -> Option<ContentFormat>

Indicates the content format of the payload, if specified.

fn accept(&self) -> Option<ContentFormat>

Indicates the content format that the sender of the message will accept for the payload of the response, if specified.

fn block2(&self) -> Option<BlockInfo>

Returns the value of the block2 option for this message, if any.

fn block1(&self) -> Option<BlockInfo>

Returns the value of the block1 option for this message, if any.

Provided methods

fn write_msg_to(&self, target: &mut dyn MessageWrite) -> Result<(), Error>

Writes this message to the given target that implements MessageWrite.

If this message has a message id (msg_id) of zero, the message id will not be written to target.

fn payload_as_str(&self) -> Option<&str>

Gets the payload as a string slice.
