Expand description

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

Required Methods§

Source

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§

Source

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.

Source

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.

Source

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.
