Implementations§

Source§

impl Options

Source

pub fn size(&self) -> usize

Returns the total wire size of this option in bytes.

Source

pub fn write<T: Write>(&self, writer: &mut T) -> Result<usize, Error>

Serializes this option to a writer.

§Errors

Returns an error if writing to the writer fails.

§Panics

Panics if the option size minus OPTION_LENGTH_SIZE_DELTA exceeds u16::MAX (unreachable in practice).
