Struct OptHeader

pub struct OptHeader { /* private fields */ }

The header of an OPT record.

The OPT record reappropriates the record header for encoding some basic information. This type provides access to this information. It consists of the record header accept for its rdlen field.

This is so that OptBuilder can safely deref to this type.

Implementations

Trait Implementations

impl Clone for OptHeader

fn clone(&self) -> OptHeader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Compose for OptHeader

fn compose_len(&self) -> usize

Returns the number of bytes this value will need without compression.

fn compose<B: BufMut>(&self, buf: &mut B)

Appends the uncompressed representation of this value to buf.

impl Debug for OptHeader

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

Formats the value using the given formatter.

impl Default for OptHeader

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for OptHeader

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
