Struct Grouping

#[non_exhaustive]
pub struct Grouping {
    pub key: Option<GroupingKey>,
}

Available on (crate features client-api-c or client-api-s) and (crate features client or server) and crate feature api only.

A grouping for partitioning the result set.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

key: Option<GroupingKey>

The key within events to use for this grouping.
