Trait Implementations

impl<T> Add for Vector2<T>

where T: Add<Output = T> + Add,

type Output = Vector2<T>

The resulting type after applying the + operator.

fn add(self, rhs: Vector2<T>) -> <Vector2<T> as Add>::Output

Performs the + operation.

Performs copy-assignment from source.

impl<T> Debug for Vector2<T>

where T: Debug,

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

Formats the value using the given formatter.

impl<T> Default for Vector2<T>

where T: Default,

fn default() -> Vector2<T>

Returns the “default value” for a type.
