Enum ark_ec::models::short_weierstrass::SWFlags

pub enum SWFlags {
    YIsPositive,
    PointAtInfinity,
    YIsNegative,
}

Flags to be encoded into the serialization. The default flags (empty) should not change the binary representation.

Variants

YIsPositive

Represents a point with positive y-coordinate by setting the MSB to 1.

PointAtInfinity

Represents the point at infinity by setting the setting the last-but-one bit to 1.

YIsNegative

Represents a point with negative y-coordinate by setting all bits to 0.

Implementations

impl SWFlags

pub fn infinity() -> Self

pub fn from_y_coordinate(y: impl Field) -> Self

pub fn is_infinity(&self) -> bool

pub fn is_positive(&self) -> Option<bool>

Trait Implementations

impl Clone for SWFlags

fn clone(&self) -> SWFlags

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SWFlags

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

Formats the value using the given formatter.

impl Default for SWFlags

fn default() -> Self

Returns the “default value” for a type.

impl Flags for SWFlags

const BIT_SIZE: usize = 2usize

The number of bits required to encode Self. This should be at most 8.

fn u8_bitmask(&self) -> u8

fn from_u8(value: u8) -> Option<Self>

fn from_u8_remove_flags(value: &mut u8) -> Option<Self>

impl PartialEq<SWFlags> for SWFlags

fn eq(&self, other: &SWFlags) -> 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.
