Enum MulticodecLength 

#[non_exhaustive]
pub enum MulticodecLength {
    Fixed(usize),
    Variable,
    NotApplicable,
}

Semantic length rule for the value described by a multicodec entry.

The primitive registry represents these cases with separate enum variants, so transport adapters cannot mistake an algorithm identifier for a key.

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.

Fixed(usize)

Values have the exact byte length carried by the variant.

Variable

Valid value lengths vary within limits defined by the owning codec.

NotApplicable

A value length is not meaningful for this registry entry.
