Enum Keys 

pub enum Keys {
    One(String),
    Several(Vec<String>),
}

What a source reads: one key, or several named ones.

Every constructor takes one, and a bare &str or String is Keys::one — so the single-key spelling every caller already wrote keeps working unchanged.

There is no prefix variant, and that is the client’s doing rather than a preference: the only listing async-nats exposes walks the whole bucket. The crate documentation says the whole of it.

Variants

One(String)

One key, whose value is the whole document.

Several(Vec<String>)

Several named keys, merged in the order given — later wins.

The rule a list of .file(..) calls already teaches: the caller wrote the list, so the list is the precedence. One get per key, because the KV API has no batch read — so the set is not read atomically.

Implementations

impl Keys

pub fn one(key: impl Into<String>) -> Self

One key, whose value is the whole document.

pub fn several<I, S>(keys: I) -> Self

where I: IntoIterator<Item = S>, S: Into<String>,

Several named keys, merged in the order given — later wins.
