Enum Trim 

pub enum Trim {
    None,
    MaxLen {
        len: u64,
        exact: bool,
        limit: Option<u64>,
    },
    MinId {
        id: Id,
        exact: bool,
        limit: Option<u64>,
    },
}

What a trim was told to cut down to.

exact is Redis’s = against ~. Without it only whole nodes go, so the stream is left at the threshold or a little over and no node is ever rewritten, which is the form to use and is why ~ exists.

limit only ever arrives with ~, because Redis refuses the two together with = and the wire layer refuses it here for the same reason: the limit is a brake on how long one command runs, and an exact trim that stopped early would not have done what it was asked.

Variants

None

No trim, which is XADD without a MAXLEN or a MINID.

MaxLen

MAXLEN n, which keeps the newest n entries.

Fields

len: u64

How many to keep.

exact: bool

Redis’s = rather than ~.

limit: Option<u64>

LIMIT, which stops the trim after that many entries have gone.

MinId

MINID id, which drops everything below id.

Fields

id: Id

The lowest ID to keep.

exact: bool

Redis’s = rather than ~.

limit: Option<u64>

LIMIT, as above.
