Enum HpkeKdfId 

#[non_exhaustive]
#[repr(u16)]
pub enum HpkeKdfId {
    HKDF_SHA256 = 1,
    HKDF_SHA384 = 2,
    HKDF_SHA512 = 3,
}

HPKE Key Derivation Functions (KDFs) identifiers.

See RFC 9180, Section 7.2.

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.

HKDF_SHA256 = 1

HKDF-SHA256

HKDF_SHA384 = 2

HKDF-SHA384

HKDF_SHA512 = 3

HKDF-SHA512

Implementations

impl HpkeKdfId

pub const fn try_from_int(x: u16) -> Result<HpkeKdfId, UnknownHpkeKdfId>

Constructs an enum value from its integer representation.

pub const fn to_int(self) -> u16

Returns the integer representation of this value.

pub const fn to_array(self) -> [u8; 2]

Returns the big-endian byte representation of this value.

pub const fn as_str(&self) -> &'static str

Returns the string representation of this value.

impl HpkeKdfId

pub const fn n_hash(&self) -> usize

Returns the length in bytes of the hash output for this KDF (Nh).

Trait Implementations

impl Clone for HpkeKdfId

fn clone(&self) -> HpkeKdfId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HpkeKdfId

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

Formats the value using the given formatter.

impl Display for HpkeKdfId

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

Formats the value using the given formatter.

impl From<HpkeKemId> for HpkeKdfId

fn from(kem: HpkeKemId) -> HpkeKdfId

Converts to this type from the input type.

impl PartialEq for HpkeKdfId

fn eq(&self, other: &HpkeKdfId) -> 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 TryFrom<u16> for HpkeKdfId

type Error = UnknownHpkeKdfId

The type returned in the event of a conversion error.

fn try_from(x: u16) -> Result<HpkeKdfId, <HpkeKdfId as TryFrom<u16>>::Error>

Performs the conversion.
