Trait Implementations

impl Add for VectorInt

type Output = VectorInt

The resulting type after applying the + operator.

fn add(self, rhs: Self) -> Self::Output

Performs the + operation.

impl Clone for VectorInt

fn clone(&self) -> VectorInt

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for VectorInt

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

Formats the value using the given formatter.

impl Div<i64> for VectorInt

type Output = VectorInt

The resulting type after applying the / operator.

fn div(self, rhs: i64) -> Self::Output

Performs the / operation.

impl From<(i64, i64)> for VectorInt

fn from(value: (i64, i64)) -> Self

Converts to this type from the input type.

impl From<VectorInt> for (i64, i64)

fn from(value: VectorInt) -> Self
