Enum ReplyKeyExpr

Source

pub enum ReplyKeyExpr {
    Any,
    MatchingQuery,
}

Available on crate feature unstable only.

Expand description

The kinds of accepted query replies.

This API has been marked as unstable: it works as advertised, but it may be changed in a future release.

The Queryable may serve glob-like key expressions. E.g., the queryable may be declared with the key expression foo/*. At the same time, it may send replies with more specific key expressions, e.g., foo/bar or foo/baz. This may cause a situation when the queryable receives a query with the key expression foo/bar and replies to it with the key expression foo/baz.

By default, this behavior is not allowed. Calling Query::reply on a query for foo/bar with key expression foo/baz will result in an error on the sending side.

But if the query is sent with the ReplyKeyExpr::Any parameter in accept_replies (for Session::get or accept_replies for Querier::get) then the reply with a disjoint key expression will be accepted for this query.

The Queryable may check this parameter with Query::accepts_replies.

Variants§

Any

Accept replies whose key expressions may not match the query key expression.
