Enum cursive_core::direction::Absolute

pub enum Absolute {
    Left,
    Up,
    Right,
    Down,
    None,
}

Absolute direction (up, down, left, right).

Variants

Left

Left

Up

Up

Right

Right

Down

Down

None

No real direction.

Used when the “direction” is across layers for instance.

Implementations

impl Absolute

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

Returns the relative direction for the given orientation.

Returns None when the direction does not apply to the given orientation (ex: Left and Vertical).

pub const fn opposite(self) -> Self

Returns the direction opposite self.

pub const fn split(self) -> (Orientation, Relative)

Splits this absolute direction into an orientation and relative direction.

For example, Right will give (Horizontal, Back).

Trait Implementations

impl Clone for Absolute

fn clone(&self) -> Absolute

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Absolute

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

Formats the value using the given formatter.

impl FromStr for Absolute

type Err = ()

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for Absolute

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 Absolute

fn eq(&self, other: &Absolute) -> 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 Resolvable for Absolute

fn from_config(config: &Config, context: &Context) -> Result<Self, Error>

Build from a config (a JSON value).

fn from_any(any: Box<dyn Any>) -> Option<Self>

where Self: Sized + Any,

Build from an Any variable.
