Enum OptionalHType 

#[non_exhaustive]
pub enum OptionalHType {
    ExtPadding,
    TimeStamp,
    Other(u8),
}

Typed H-Type for an Optional extension header (H-LEN = 1..=5, RFC 4326 §5).

Optional H-Types share the H-Type byte namespace with Mandatory H-Types but are distinguished by a non-zero H-LEN.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

ExtPadding

Extension-Padding — H-Type 0x00, H-LEN 1..=5 (RFC 4326 §5.3).

TimeStamp

TimeStamp — H-Type 0x01, H-LEN = 3 (RFC 5163 §3.3).

Other(u8)

An unrecognised optional H-Type.

Implementations

impl OptionalHType

pub fn from_u8(raw: u8) -> OptionalHType

Decode from the raw 8-bit H-Type byte.

pub fn to_u8(self) -> u8

Encode back to the raw 8-bit H-Type byte.

pub fn name(&self) -> &'static str

Spec label for this optional H-Type.

Trait Implementations

impl Clone for OptionalHType

fn clone(&self) -> OptionalHType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for OptionalHType

impl Debug for OptionalHType

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

Formats the value using the given formatter.

impl Display for OptionalHType

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

Formats the value using the given formatter.

impl Eq for OptionalHType

impl Hash for OptionalHType

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for OptionalHType

fn eq(&self, other: &OptionalHType) -> 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.

impl Serialize for OptionalHType

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
