Enum Symbol 

pub enum Symbol {
    DirectionUp,
    DirectionRight,
    DirectionDown,
    DirectionLeft,
    Diamond,
    Hexagon,
    Circle,
}

A symbol a cell can name: a direction an arrow points in, or a shape a terminal stands on.

Closed rather than a name, so that a symbol the core does not know cannot arrive and be rendered as a space: a misspelled style and a missing pair answer alike, and this is the half that must not. Self::ALL is the order a sheet prints the vocabulary in.

Variants

DirectionUp

An arrow pointing up.

DirectionRight

An arrow pointing right.

DirectionDown

An arrow pointing down.

DirectionLeft

An arrow pointing left.

Diamond

A diamond, which points nowhere.

Hexagon

A hexagon, which points nowhere.

Circle

A circle, which points nowhere.

Implementations

impl Symbol

pub const ALL: [Symbol; 7]
