Enum redis_async::resp::RespValue [−][src]
pub enum RespValue { Nil, Array(Vec<RespValue>), BulkString(Vec<u8>), Error(String), Integer(i64), SimpleString(String), }
A single RESP value, this owns the data that is read/to-be written to Redis.
It is cloneable to allow multiple copies to be delivered in certain circumstances, e.g. multiple subscribers to the same topic.
Variants
Nil
Array(Vec<RespValue>)
Zero, one or more other RespValue
s.
BulkString(Vec<u8>)
A bulk string. In Redis terminology a string is a byte-array, so this is stored as a
vector of u8
s to allow clients to interpret the bytes as appropriate.
Error(String)
An error from the Redis server
Integer(i64)
Redis documentation defines an integer as being a signed 64-bit integer: https://redis.io/topics/protocol#resp-integers
SimpleString(String)

[src]
fn from_resp_int(resp: RespValue) -> Result<RespValue, Error>
fn from_resp(resp: RespValue) -> Result<Self, Error>
[src]
fn from_resp(resp: RespValue) -> Result<Self, Error>
Return a Result
containing either Self
