Expand description

Internal low-level redis value enum.

Variants

Nil

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.

Data(Vec<u8>)

An arbitary binary data.

Bulk(Vec<Value>)

A bulk response of more data. This is generally used by redis to express nested structures.

Status(String)

A status response.

Okay

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

Returns a copy of the value. Read more

Performs copy-assignment from source. Read more

Formats the value using the given formatter. Read more

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

This method tests for self and other values to be equal, and is used by ==. Read more

This method tests for !=.
