Enum cursive::direction::Direction

pub enum Direction {
    Abs(Absolute),
    Rel(Relative),
}

Represents a direction, either absolute or orientation-dependent.

• Absolute directions are Up, Down, Left, and Right.
• Relative directions are Front and Back.

Variants

Abs(Absolute)

An absolute direction.

Rel(Relative)

A direction relative to the current orientation.

Implementations

impl Direction

pub fn relative(self, orientation: Orientation) -> Option<Relative>

Returns the relative direction for the given orientation.

Some combination have no corresponding relative position. For example, Direction::Abs(Up) means nothing for Orientation::Horizontal.

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

Returns the absolute direction in the given orientation.

pub fn opposite(self) -> Direction

Returns the direction opposite self.

pub fn back() -> Direction

Shortcut to create Direction::Rel(Relative::Back)

pub fn front() -> Direction

Shortcut to create Direction::Rel(Relative::Front)

pub fn left() -> Direction

Shortcut to create Direction::Abs(Absolute::Left)

pub fn right() -> Direction

Shortcut to create Direction::Abs(Absolute::Right)

pub fn up() -> Direction

Shortcut to create Direction::Abs(Absolute::Up)

pub fn down() -> Direction

Shortcut to create Direction::Abs(Absolute::Down)

pub fn none() -> Direction

Shortcut to create Direction::Abs(Absolute::None)
