Struct AnySignature 

pub struct AnySignature {
    pub variant: AnyPublicKeyVariant,
    pub bytes: Vec<u8>,
}

A signature that can be any supported signature scheme.

Fields

variant: AnyPublicKeyVariant

The signature scheme variant.

bytes: Vec<u8>

The raw signature bytes.

Implementations

impl AnySignature

pub fn new(variant: AnyPublicKeyVariant, bytes: Vec<u8>) -> Self

Creates a new AnySignature.

pub fn ed25519(signature: &Ed25519Signature) -> Self

Available on crate feature ed25519 only.

Creates an Ed25519 signature.

pub fn secp256k1(signature: &Secp256k1Signature) -> Self

Available on crate feature secp256k1 only.

Creates a Secp256k1 signature.

pub fn secp256r1(signature: &Secp256r1Signature) -> Self

Available on crate feature secp256r1 only.

Creates a Secp256r1 signature.

pub fn to_bcs_bytes(&self) -> Vec<u8>

Serializes to BCS AnySignature bytes.

Most variants use variant_byte || ULEB128(len) || payload.

On Aptos, discriminant 2 is shared by bare Secp256r1Ecdsa signatures (64-byte payload) and the WebAuthn variant, which embeds a PartialAuthenticatorAssertionResponse struct without an outer ULEB128 length prefix after the enum tag. When this struct is present, the first payload byte is 0x00 (AssertionSignature::Secp256r1Ecdsa). For that shape we serialize as 0x02 || payload to match the chain and crate::account::WebAuthnAccount.

pub fn from_bcs_bytes(bytes: &[u8]) -> AptosResult<Self>

Parses BCS AnySignature bytes from the wire.

For variants other than Secp256r1 (2), this expects variant || ULEB128(len) || payload.

For discriminant 2, Aptos uses two layouts:

• Bare ECDSA: 0x02 || ULEB128(64) || 64-byte signature. The length prefix always begins with 0x40 when 64 is encoded as a single ULEB128 byte.
• WebAuthn: 0x02 || BCS(PartialAuthenticatorAssertionResponse), which begins with 0x00 (AssertionSignature::Secp256r1Ecdsa) — no outer ULEB128 wrapping the struct.

Errors

Returns AptosError::InvalidSignature if the slice is empty, the variant byte is unknown, the length prefix is malformed, the payload is truncated, or trailing bytes remain after the declared signature bytes.

Trait Implementations

impl Clone for AnySignature

fn clone(&self) -> AnySignature

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AnySignature

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

Formats the value using the given formatter.

impl PartialEq for AnySignature

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