Implementations

impl Options

pub fn size(&self) -> usize

Returns the total wire size of this option in bytes.

Trait Implementations

impl Clone for Options

fn clone(&self) -> Options

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Options

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

Formats the value using the given formatter.

impl Encode for Options

fn encode(&self, writer: &mut impl Write) -> Result<usize, Self::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).

type Error = Error

Per-implementation error; constructible from an I/O embedded_io::ErrorKind so the fixed-width write_* leaf helpers lift through ?.

fn encoded_size(&self) -> Result<usize, Self::Error>

Exact number of bytes encode will write.

fn encode_to_slice( &self, buf: &mut [u8], ) -> Result<usize, EncodeToSliceError<Self::Error>>

Encode into a fixed slice, reporting needed/available (InsufficientBuffer) instead of a bare embedded_io::ErrorKind::WriteZero when the slice is too small, and hiding the &mut &mut [u8] cursor re-borrow every fixed-buffer call site otherwise writes by hand.

impl Eq for Options

impl PartialEq for Options

fn eq(&self, other: &Options) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
