Trait for types that allow you to insert CoAP options into them.

Required methods

fn insert_option_with_bytes(
    &mut self,
    key: OptionNumber,
    value: &[u8]
) -> Result<(), Error>

Inserts an option into the message with the given bytes as the value. Calling this method with out-of-order keys will incur a significant performance penalty.

Provided methods

fn insert_option_empty(&mut self, key: OptionNumber) -> Result<(), Error>

Inserts an option into the message with no value. Calling this method with out-of-order keys will incur a significant performance penalty.

fn insert_option_with_str(
    &mut self,
    key: OptionNumber,
    value: &str
) -> Result<(), Error>

Inserts an option into the message with a string value. Calling this method with out-of-order keys will incur a significant performance penalty.

fn insert_option_with_u32(
    &mut self,
    key: OptionNumber,
    value: u32
) -> Result<(), Error>

Inserts an option into the message with an integer value. Calling this method with out-of-order keys will incur a significant performance penalty.
