Trait Implementations

impl<S> Clone for LineEquation<S>

where S: Clone,

fn clone(&self) -> LineEquation<S>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<S> Debug for LineEquation<S>

where S: Debug,

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

Formats the value using the given formatter.

impl<S> PartialEq for LineEquation<S>

where S: PartialEq,

fn eq(&self, other: &LineEquation<S>) -> 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.

where S: Eq,

impl<S> StructuralPartialEq for LineEquation<S>
