Enum Moved 

pub enum Moved {
    Missing,
    Taken,
    Unsupported,
    Ok,
}

What a rename or a copy did.

Variants

Missing

There was no source key, so there was nothing to move.

Taken

The destination was there and the caller said not to write over it.

Unsupported

The source holds something there is no way to copy.

A foreign body is owned by the engine above this crate and there is no generic way to ask one for a duplicate of itself. A graph could grow a deep copy and a vector index probably should not have one at all, so the decision belongs to whichever of them is under the key rather than here. Answered rather than panicked so the wire can say so in a sentence.

Ok

It happened.

Implementations

impl Moved

So that a caller can write ? on a rename without unpacking the enum.

Moved::Taken is not an error here, because for RENAMENX it is the whole answer and for RENAME it cannot happen.

pub fn found(self) -> Result<Moved>

The source was there, or the error RENAME gives when it was not.

Errors

yo_common::Code::Invalid with Redis’s no such key for Moved::Missing.
