Struct HpkeKdf 

pub struct HpkeKdf(pub u16);

The Key Derivation Function (Kdf) type for HPKE operations. Listed by IANA, as specified in RFC 9180 Section 7.2

Protocol enumerations in rustls are represented with a struct, which contains the numeric value used on the wire (in this case, u16). Each known value has a named const item on this type – this can be used in a match arm or to access the numeric value.

If a known value does not exist for a value you need, you can simply create it locally:

pub const MyValue: HpkeKdf = HpkeKdf(123);

The Debug impl for this type also looks up and pretty-prints known named items. Unknown values are formatted in hexadecimal.

Implementations

impl HpkeKdf

pub const HKDF_SHA256: Self

Trait Implementations

impl Clone for HpkeKdf

fn clone(&self) -> HpkeKdf

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HpkeKdf

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

Formats the value using the given formatter.

impl Default for HpkeKdf

fn default() -> Self

Returns the “default value” for a type.

impl From<HpkeKdf> for u16

fn from(x: HpkeKdf) -> Self

Converts to this type from the input type.

impl From<u16> for HpkeKdf

fn from(x: u16) -> Self

Converts to this type from the input type.

impl Hash for HpkeKdf

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

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 HpkeKdf

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