EcdsaSigningScheme

Enum EcdsaSigningScheme

pub enum EcdsaSigningScheme {
    Eip712,
    EthSign,
}

Expand description

ECDSA-only signing schemes (EIP-712 or EIP-191).

A subset of SigningScheme limited to the two schemes that produce standard ECDSA signatures. Use into_signing_scheme to widen to the full enum when needed.

§Example

use cow_types::{EcdsaSigningScheme, SigningScheme};

let ecdsa = EcdsaSigningScheme::Eip712;
let full: SigningScheme = ecdsa.into();
assert_eq!(full, SigningScheme::Eip712);

Variants§

Eip712

Standard EIP-712 typed-data signature (default).

EthSign

Legacy eth_sign (EIP-191) signature.

Implementations§

impl EcdsaSigningScheme

pub const fn into_signing_scheme(self) -> SigningScheme

Widen to the full SigningScheme enum.

§Returns

SigningScheme::Eip712 or SigningScheme::EthSign.

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

Returns the lowercase string used by the CoW Protocol API.

§Returns

"eip712" or "ethsign".

pub const fn is_eip712(self) -> bool

Returns true if the EIP-712 typed-data scheme is selected.

pub const fn is_eth_sign(self) -> bool

Returns true if the legacy EIP-191 (eth_sign) scheme is selected.
