Enum SquareColor 

#[non_exhaustive]
pub enum SquareColor {
    Light,
    Dark,
}

Colour of a square — the default binary partition used by chess (and the default type parameter C for Constraint / crate::Problem).

For N-way colour partitions, define your own enum and use it as the C type parameter. Any Copy + Eq + Hash + Debug type satisfies ColorKind.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Light

Light-coloured square.

Dark

Dark-coloured square.

Trait Implementations

impl Clone for SquareColor

fn clone(&self) -> SquareColor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SquareColor

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SquareColor

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for SquareColor

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 SquareColor

fn eq(&self, other: &SquareColor) -> 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 SquareColor

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for SquareColor

impl Eq for SquareColor

impl StructuralPartialEq for SquareColor
