Enum ChaChaVariant 

#[non_exhaustive]
pub enum ChaChaVariant {
    ChaCha20,
    ChaCha12,
    ChaCha8,
}

Number of rounds of the ChaCha block function.

ChaCha20 is the standard (RFC 8439) variant. The reduced-round ChaCha12 and ChaCha8 are faster but have a smaller security margin; only the CryptoCell engine supports them.

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.

ChaCha20

20 rounds (RFC 8439).

ChaCha12

12 rounds.

ChaCha8

8 rounds.
