The shard’s response to a request.

Variants

Value(Option<Value>)

A value (or None for a cache miss).

Ok

Simple acknowledgement (e.g. SET).

Integer(i64)

Integer result (e.g. INCR, DECR).

Bool(bool)

Boolean result (e.g. DEL, EXISTS, EXPIRE).

Ttl(TtlResult)

TTL query result.

OutOfMemory

Memory limit reached and eviction policy is NoEviction.

KeyCount(usize)

Key count for a shard (DBSIZE).

Stats(KeyspaceStats)

Full stats for a shard (INFO).

Len(usize)

Integer length result (e.g. LPUSH, RPUSH, LLEN).

Array(Vec<Bytes>)

Array of bulk values (e.g. LRANGE).

TypeName(&'static str)

The type name of a stored value.

ZAddLen

ZADD result: count for the client + actually applied members for AOF.

Fields

count: usize

applied: Vec<(f64, String)>

ZRemLen

ZREM result: count for the client + actually removed members for AOF.

Fields

count: usize

removed: Vec<String>

Score(Option<f64>)

Float score result (e.g. ZSCORE).

Rank(Option<usize>)

Rank result (e.g. ZRANK).

ScoredArray(Vec<(String, f64)>)

Scored array of (member, score) pairs (e.g. ZRANGE).

WrongType

Command used against a key holding the wrong kind of value.

Err(String)

An error message.

Scan

Scan result: next cursor and list of keys.

Fields

cursor: u64

keys: Vec<String>

HashFields(Vec<(String, Bytes)>)

HGETALL result: all field-value pairs.

HDelLen

HDEL result: removed count + field names for AOF.

Fields

count: usize

removed: Vec<String>

StringArray(Vec<String>)

Array of strings (e.g. HKEYS).

OptionalArray(Vec<Option<Bytes>>)

HMGET result: array of optional values.
