Enum StreamTrimStrategy 

#[non_exhaustive]
pub enum StreamTrimStrategy {
    MaxLen(StreamTrimmingMode, usize, Option<usize>),
    MinId(StreamTrimmingMode, String, Option<usize>),
}

A stream trim strategy.

Mirrors redis-rs’s streams::StreamTrimStrategy type.

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.

MaxLen(StreamTrimmingMode, usize, Option<usize>)

Evict entries while the stream is longer than the threshold (MAXLEN).

MinId(StreamTrimmingMode, String, Option<usize>)

Evict entries with IDs lower than the threshold (MINID).

Implementations

impl StreamTrimStrategy

pub fn maxlen(trim: StreamTrimmingMode, max_entries: usize) -> Self

Trim to at most max_entries entries (MAXLEN).

pub fn minid(trim: StreamTrimmingMode, stream_id: impl Into<String>) -> Self

Trim entries with IDs lower than stream_id (MINID).

pub fn limit(self, limit: usize) -> Self

Limit the number of entries evicted in a single operation (LIMIT).
