Enum RenameOutcome 

pub enum RenameOutcome {
    Renamed,
    NoSuchSrc,
    DstExists,
}

Outcome of Store::rename — three-way result so the dispatch layer can pick the right RESP frame (+OK / -ERR no such key / :0 for RENAMENX-with-existing-dst).

Variants

Renamed

Source removed, destination created (overwriting any prior dst).

NoSuchSrc

Source key doesn’t exist.

DstExists

RENAMENX only — destination already exists, no rename done.

impl PartialEq for RenameOutcome

fn eq(&self, other: &RenameOutcome) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
