Implementations

impl Signature

pub const ED25519_LENGTH: usize

The length in bytes of an Ed25519 signature,

pub const SECP256K1_LENGTH: usize

The length in bytes of a secp256k1 signature

pub fn new_ed25519(bytes: [u8; 64]) -> Result<Self>

Constructs a new Ed25519 variant from a byte array.

pub fn new_secp256k1(bytes: [u8; 64]) -> Result<Self>

Constructs a new secp256k1 variant from a byte array.

pub fn ed25519_from_bytes<T: AsRef<[u8]>>(bytes: T) -> Result<Self>

Constructs a new Ed25519 variant from a byte slice.

pub fn secp256k1_from_bytes<T: AsRef<[u8]>>(bytes: T) -> Result<Self>

Constructs a new secp256k1 variant from a byte slice.

pub fn to_hex(&self) -> String

Converts the signature to hex, where the first byte represents the algorithm tag.

pub fn from_hex<T: AsRef<[u8]>>(input: T) -> Result<Self>

Tries to decode a signature from its hex-representation. The hex format should be as produced by Signature::to_hex().

Trait Implementations

impl AsRef<[u8]> for Signature

fn as_ref(&self) -> &[u8]

Performs the conversion.

impl Clone for Signature

fn clone(&self) -> Signature

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for Signature

impl DataSize for Signature where
    [u8; 64]: DataSize, 

const IS_DYNAMIC: bool

If true, the type has a heap size that can vary at runtime, depending on the actual value.

const STATIC_HEAP_SIZE: usize

The amount of space a value of the type always occupies. If IS_DYNAMIC is false, this is the total amount of heap memory occupied by the value. Otherwise this is a lower bound.

fn estimate_heap_size(&self) -> usize

Estimates the size of heap memory taken up by this value.

impl Debug for Signature

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Signature

fn deserialize<D: Deserializer<'de>>(
    deserializer: D
) -> StdResult<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl Display for Signature

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

Formats the value using the given formatter.

impl Eq for Signature

impl Hash for Signature

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given Hasher.

impl Ord for Signature

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<Signature> for Signature

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl PartialOrd<Signature> for Signature

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

#[must_use]fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

#[must_use]fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

#[must_use]fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

#[must_use]fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for Signature

fn serialize<S: Serializer>(&self, serializer: S) -> StdResult<S::Ok, S::Error>

Serialize this value into the given Serde serializer.
