Trait Implementations

impl Add for Dir

type Output = Dir

The resulting type after applying the + operator.

fn add(self, other: Self) -> Self

Performs the + operation.

impl Clone for Dir

fn clone(&self) -> Dir

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Dir

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

Formats the value using the given formatter.

impl Default for Dir

fn default() -> Dir

Returns the “default value” for a type.

impl PartialEq for Dir

fn eq(&self, other: &Dir) -> 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 Copy for Dir

impl Eq for Dir
