Enum StreamEntryDeletionPolicy 

#[non_exhaustive]
pub enum StreamEntryDeletionPolicy {
    KeepRef,
    DelRef,
    Acked,
}

Controls how consumer-group references are handled when stream entries are removed. Shared by every entry-removing command since Redis 8.2 — here the trimming clause of xadd, xtrim, xdelex and xackdel.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

KeepRef

Remove the entry but keep consumer-group references (default, preserves pre-8.2 behaviour).

DelRef

Remove the entry and all references to it from every consumer group’s PEL.

Acked

Only remove entries already acknowledged by all consumer groups.
