Enum Coordinates 

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

Available on crate feature point only.

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

Variants

Identity point (a.k.a. point at infinity)

Compact

Compact curve point

Fields

x: &'a GenericArray<u8, Size>

x-coordinate

Compressed

Compressed curve point

Fields

x: &'a GenericArray<u8, Size>

x-coordinate

y_is_odd: bool

Is the y-coordinate odd?

Uncompressed

Uncompressed curve point

Fields

x: &'a GenericArray<u8, Size>

x-coordinate

y: &'a GenericArray<u8, Size>

y-coordinate

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 duplicate 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.

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

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

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

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
