    PresentAndHashEqual(Vec<u8>),
    AbsentOrHashEqual(Vec<u8>),
    AbsentOrNotHashEqual(Vec<u8>),
    Unconditional,
}

Condition for set-if-hash operations (comparing hashes instead of full values).

Variants

PresentAndNotHashEqual(Vec<u8>)

Set only if the key exists and the hash of its current value does not match the provided hash.

PresentAndHashEqual(Vec<u8>)

Set only if the key exists and the hash of its current value matches the provided hash.

AbsentOrHashEqual(Vec<u8>)

Set if the key does not exist, or if it exists and the hash of its current value matches the provided hash.

AbsentOrNotHashEqual(Vec<u8>)

Set if the key does not exist, or if it exists and the hash of its current value does not match the provided hash.

Unconditional
