Enum redis::Value [−][src]
Expand description
Internal low-level redis value enum.
Variants
A nil response from the server.
Int(i64)
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.
An arbitary binary data.
A bulk response of more data. This is generally used by redis to express nested structures.
Status(String)
A status response.
A status response which represents the string “OK”.
Implementations
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.
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.
Returns an &[Value]
if self
is compatible with a sequence type
Returns an iterator of (&Value, &Value)
if self
is compatible with a map type
Trait Implementations
Given a redis Value
this attempts to convert it into the given
destination type. If that fails because it’s not compatible an
appropriate error is generated. Read more
Similar to from_redis_value
but constructs a vector of objects
from another vector of values. This primarily exists internally
to customize the behavior for vectors of tuples. Read more
