Implementations§

§

impl Parity

pub const fn chain_id(&self) -> Option<u64>

Returns the chain ID associated with the V value, if this signature is replay-protected by EIP-155.

pub const fn has_eip155_value(&self) -> bool

Returns true if the signature is replay-protected by EIP-155.

This is true if the V value is 35 or greater. Values less than 35 are either not replay protected (27/28), or are invalid.

pub const fn y_parity(&self) -> bool

Return the y-parity as a boolean.

pub const fn y_parity_byte(&self) -> u8

Return the y-parity as 0 or 1

pub const fn y_parity_byte_non_eip155(&self) -> Option<u8>

Return the y-parity byte as 27 or 28, in the case of a non-EIP155 signature.

pub const fn to_u64(&self) -> u64

Return the corresponding u64 V value.

pub const fn inverted(&self) -> Parity

Inverts the parity.

pub const fn strip_chain_id(&self) -> Parity

Converts an EIP-155 V value to a non-EIP-155 V value.

This is a nop for non-EIP-155 values.

pub const fn with_chain_id(self, chain_id: u64) -> Parity

Applies EIP-155 with the given chain ID.

pub const fn recid(&self) -> RecoveryId

Available on crate feature k256 only.

Determines the recovery ID.

pub const fn to_parity_bool(self) -> Parity

Convert to a parity bool, dropping any V information.
