Enum CompositionGuide 

#[non_exhaustive]
pub enum CompositionGuide {
    Thirds,
    Divisions(u32),
    Squares(u32),
    GoldenRatio,
}

The lines a RuleOfThirdsGrid draws.

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.

Thirds

Two lines each way, at a third and two thirds.

Divisions(u32)

This many equal parts each way, such as a fine grid to level a horizon.

Squares(u32)

Square cells, this many along the shorter side.

GoldenRatio

Two lines each way, at the golden ratio.
