Enum Encoding 

#[non_exhaustive]
pub enum Encoding {
    Hex,
    Base64,
    Raw,
}

How the digest is written out.

The reference package calls this encoding. Hexadecimal is its default and the one a cache key is normally written in; base64 is shorter, and raw bytes are what a caller wants when the digest is fed to something else.

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.

Hex

Lowercase hexadecimal, two characters per byte. The reference’s default.

Base64

Standard base64 with + and /, padded with =.

Raw

The raw digest bytes.
