Enum KeyType 

#[non_exhaustive]
pub enum KeyType {
    Ed25519,
    X25519,
    P256,
    P384,
    P521,
    Secp256k1,
    Bls12381G2,
    Unknown,
}

Known cryptographic key types.

This enum is #[non_exhaustive]: new algorithms (hybrid schemes, future NIST standards, vendor-specific key types) will be added in minor releases without breaking match-all arms.

No Default impl is provided on purpose: a key without a known algorithm is a programming error in this crate, not a sensible default state. KeyType::Unknown exists for parsing paths that receive an unrecognised curve or codec identifier.

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.

Ed25519

X25519

P256

P384

P521

Secp256k1

Bls12381G2

BLS12-381 G2 public key — the verification key of a BBS+ issuer (bbs-2023 Data-Integrity cryptosuite). A 96-byte compressed G2 point, multicodec 0xeb.

Unknown

Unrecognised or unsupported key type. Produced by parsing paths on unknown curve identifiers; should never be constructed directly.

Trait Implementations

impl Clone for KeyType

fn clone(&self) -> KeyType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for KeyType

impl Debug for KeyType

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for KeyType

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for KeyType

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

Formats the value using the given formatter.

impl Eq for KeyType

impl PartialEq for KeyType

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for KeyType

impl TryFrom<&str> for KeyType

type Error = CryptoError

The type returned in the event of a conversion error.

fn try_from(value: &str) -> Result<Self, Self::Error>

Performs the conversion.

impl Zeroize for KeyType

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not “optimized away” by the compiler.
