Enum redis::Value
[−]
[src]
pub enum Value {
Nil,
Int(i64),
Data(Vec<u8>),
Bulk(Vec<Value>),
Status(String),
Okay,
}Internal low-level redis value enum.
Variants
Nil | A nil response from the server. |
Int | An integer response. Note that there are a few situations in which redis actually returns a string for an integer which is why this library generally treats integers and strings the same for all numeric responses. |
Data | An arbitary binary data. |
Bulk | A bulk response of more data. This is generally used by redis to express nested structures. |
Status | A status response. |
Okay | A status response which represents the string "OK". |
Methods
impl Value
Values are generally not used directly unless you are using the
more low level functionality in the library. For the most part
this is hidden with the help of the FromRedisValue trait.
While on the redis protocol there is an error type this is already separated at an early point so the value only holds the remaining types.
fn looks_like_cursor(&self) -> bool
Checks if the return value looks like it fulfils the cursor protocol. That means the result is a bulk item of length two with the first one being a cursor and the second a bulk response.
