Enum BiomeModifierError 

#[non_exhaustive]
pub enum BiomeModifierError {
    InvalidId,
    Duplicate,
    EmptyList,
    InvalidName,
    UnknownStep,
    InvalidSpawner,
    InvalidCost,
    InvalidValue,
}

Why a biome modifier was refused (Registrar::declare_biome_modifier).

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.

InvalidId

The modifier’s own id is empty or in a namespace the declaring mod does not own.

Duplicate

Another modifier of the mod has the id.

EmptyList

A list that must name something is empty.

InvalidName

An id or tag is not namespaced (mymod:thing, a tag with a leading #).

UnknownStep

A generation step name vanilla does not have.

InvalidSpawner

A spawner outside signed integer bounds, with an empty group, or inverted group bounds.

InvalidCost

A spawn cost that is not a finite number.

InvalidValue

A climate number that is not finite, a colour above 0xFFFFFF, or a temperature modifier other than none or frozen.
