Enum Kem 

#[non_exhaustive]
#[repr(u16)]
pub enum Kem {
    DhP256HkdfSha256 = 16,
    DhP384HkdfSha384 = 17,

}

Kem represents an asymmetric key encapsulation mechanism, as per RFC9180§7.1. Currently only four of the options listed in the hpke draft are available.

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.

Implementations

impl Kem

pub fn gen_keypair(self) -> Keypair

generate a Keypair for this Kem.

Trait Implementations

impl Clone for Kem

fn clone(&self) -> Kem

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Kem

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

Formats the value using the given formatter.

impl FromStr for Kem

type Err = IdLookupError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl PartialEq for Kem

fn eq(&self, other: &Kem) -> 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 Kem

type Error = TryFromPrimitiveError<Kem>

The type returned in the event of a conversion error.

fn try_from(number: u16) -> Result<Self, TryFromPrimitiveError<Self>>

Performs the conversion.

impl TryFromPrimitive for Kem

const NAME: &'static str = "Kem"

type Primitive = u16

type Error = TryFromPrimitiveError<Kem>

fn try_from_primitive( number: Self::Primitive, ) -> Result<Self, TryFromPrimitiveError<Self>>

impl Copy for Kem

impl Eq for Kem

impl StructuralPartialEq for Kem
