Enum Direction 

pub enum Direction {
    H,
    V,
    DP,
    DN,
}

Line direction. The unit step delta() defines the coordinate convention the whole format depends on, so it is normative.

Variants

H

Horizontal, step (1, 0).

V

Vertical, step (0, 1).

DP

Diagonal “up”, step (1, -1).

DN

Diagonal “down”, step (1, 1).

Implementations

impl Direction

pub const ALL: [Direction; 4]

All four directions.

pub fn delta(self) -> (i16, i16)

Unit step along the line, smaller-coordinate end first. Normative.

pub fn code(self) -> &'static str

Wire code: "H", "V", "DP", "DN".

pub fn from_code(s: &str) -> Option<Direction>

Parse a wire code.

Trait Implementations

impl Clone for Direction

fn clone(&self) -> Direction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Direction

impl Debug for Direction

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Direction

fn deserialize<D: Deserializer<'de>>(d: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl Eq for Direction

impl Hash for Direction

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 Direction

fn eq(&self, other: &Direction) -> 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 Serialize for Direction

fn serialize<S: Serializer>(&self, s: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.
