Implementations

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

where Size: ModulusSize,

pub fn tag(&self) -> Tag

Get the tag octet needed to encode this set of Coordinates

Trait Implementations

impl<'a, Size> Clone for Coordinates<'a, Size>

where Size: Clone + ModulusSize,

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 for Coordinates<'a, Size>

where Size: Debug + ModulusSize,

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

Formats the value using the given formatter.

impl<'a, Size> PartialEq for Coordinates<'a, Size>

where Size: PartialEq + ModulusSize,

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 for Coordinates<'a, Size>

where Size: Copy + ModulusSize,

impl<'a, Size> Eq for Coordinates<'a, Size>

where Size: Eq + ModulusSize,

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

where Size: ModulusSize,
