Enum secp256k1::Parity

pub enum Parity {
    Even,
    Odd,
}

Represents the parity passed between FFI function calls.

Variants

Even

Even parity.

Odd

Odd parity.

Implementations

impl Parity

pub fn to_u8(self) -> u8

Converts parity into an integer (byte) value.

This returns 0 for even parity and 1 for odd parity.

pub fn to_i32(self) -> i32

Converts parity into an integer value.

This returns 0 for even parity and 1 for odd parity.

pub fn from_u8(parity: u8) -> Result<Parity, InvalidParityValue>

Constructs a Parity from a byte.

The only allowed values are 0 meaning even parity and 1 meaning odd. Other values result in error being returned.

pub fn from_i32(parity: i32) -> Result<Parity, InvalidParityValue>

Constructs a Parity from a signed integer.

The only allowed values are 0 meaning even parity and 1 meaning odd. Other values result in error being returned.

Trait Implementations

impl BitXor<Parity> for Parity

Returns even parity if the operands are equal, odd otherwise.

type Output = Parity

The resulting type after applying the ^ operator.

fn bitxor(self, rhs: Parity) -> Self::Output

Performs the ^ operation.

impl Clone for Parity

fn clone(&self) -> Parity

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Parity

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

Formats the value using the given formatter.

impl From<Parity> for i32

The conversion returns 0 for even parity and 1 for odd.

fn from(parity: Parity) -> i32

Converts to this type from the input type.

impl From<Parity> for u8

The conversion returns 0 for even parity and 1 for odd.

fn from(parity: Parity) -> u8

Converts to this type from the input type.

impl Hash for Parity

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,
    Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Parity

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<Parity> for Parity

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<Parity> for Parity

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

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

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

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

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

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

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

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

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 TryFrom<i32> for Parity

Even for 0, Odd for 1, error for anything else

type Error = InvalidParityValue

The type returned in the event of a conversion error.

fn try_from(parity: i32) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<u8> for Parity

Even for 0, Odd for 1, error for anything else

type Error = InvalidParityValue

The type returned in the event of a conversion error.

fn try_from(parity: u8) -> Result<Self, Self::Error>

Performs the conversion.
