Implementations

impl Signature

pub const fn len() -> usize

Size of this object in bytes.

impl Signature

pub fn verify( &self, pk: &PublicKey, context: &[u8], message: &[u8], ) -> Result<()>

Verify signature.

pub fn verify_raw(&self, pk: &PublicKey, msg: &[u8]) -> Result<()>

Verify signature without applying domain separation.

Trait Implementations

impl AsRef<[u8]> for Signature

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

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Signature

fn clone(&self) -> Signature

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Signature

impl Debug for Signature

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

Formats the value using the given formatter.

impl Decode for Signature

fn try_default() -> Result<Self, DecodeError>

Try to decode from a missing/null/undefined value.

fn try_from_cbor_value(value: Value) -> Result<Self, DecodeError>

Try to decode from a given CBOR value.

fn try_from_cbor_value_default(value: Value) -> Result<Self, DecodeError>

where Self: Sized,

Try to decode from a given CBOR value, calling try_default in case the value is null or undefined.

impl Default for Signature

fn default() -> Self

Returns the “default value” for a type.

impl Display for Signature

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

Formats the value using the given formatter.

impl Encode for Signature

fn into_cbor_value(self) -> Value

Encode the type into a CBOR Value.

fn is_empty(&self) -> bool

Whether the value is equal to the empty value for the type.

impl Eq for Signature

impl From<&'static str> for Signature

fn from(s: &'static str) -> Signature

Converts to this type from the input type.

impl From<&[u8]> for Signature

fn from(b: &[u8]) -> Signature

Converts to this type from the input type.

impl From<Signature> for [u8; 64]

fn from(b: Signature) -> Self

Converts to this type from the input type.

impl From<Vec<u8>> for Signature

fn from(v: Vec<u8>) -> Signature

Converts to this type from the input type.

impl FromStr for Signature

type Err = FromHexError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Signature, FromHexError>

Parses a string s to return a value of this type.

impl Hash for Signature

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

where H: Hasher,

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl LowerHex for Signature

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

Formats the value using the given formatter.

impl Ord for Signature

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

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Signature

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

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl PartialOrd for Signature

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

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

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

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

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

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

impl Zeroize for Signature

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.
