Enum cursive_core::direction::Relative

pub enum Relative {
    Front,
    Back,
}

Direction relative to an orientation.

Variants

Front

Front relative direction.

• Horizontally, this means Left
• Vertically, this means Up

Back

Back relative direction.

• Horizontally, this means Right
• Vertically, this means Down.

Implementations

impl Relative

pub const fn absolute(self, orientation: Orientation) -> Absolute

Returns the absolute direction in the given orientation.

pub fn pick<T>(self, (front, back): (T, T)) -> T

Picks one of the two values in a tuple.

First one is self is Front, second one if self is Back.

pub const fn swap(self) -> Self

Returns the other relative direction.

pub const fn a_to_b(a: usize, b: usize) -> Option<Self>

Returns the position of a relative to b.

If a < b, it would be Front. If a > b, it would be Back. If a == b, returns None.

Trait Implementations

impl Clone for Relative

fn clone(&self) -> Relative

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Relative

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

Formats the value using the given formatter.

impl Hash for Relative

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Relative

fn eq(&self, other: &Relative) -> 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.
