Enum Coordinates

pub enum Coordinates<'a, Size: ModulusSize> {
    Identity,
    Compact {
        x: &'a GenericArray<u8, Size>,
    },
    Compressed {
        x: &'a GenericArray<u8, Size>,

        y: &'a GenericArray<u8, Size>,
    },
}

Enum representing the coordinates of either compressed or uncompressed SEC1-encoded elliptic curve points.

Implementations

impl<'a, Size: ModulusSize> Coordinates<'a, Size>

pub fn tag(&self) -> Tag

Get the tag octet needed to encode this set of Coordinates

Trait Implementations

impl<'a, Size: Clone + ModulusSize> Clone for Coordinates<'a, Size>

fn clone(&self) -> Coordinates<'a, Size>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a, Size: Debug + ModulusSize> Debug for Coordinates<'a, Size>

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

Formats the value using the given formatter.

impl<'a, Size: PartialEq + ModulusSize> PartialEq for Coordinates<'a, Size>

fn eq(&self, other: &Coordinates<'a, Size>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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