pub struct InfoDict { /* private fields */ }
Expand description

An info dictionary type.

Implementations

This type provides convenient access to key/value data returned by the “INFO” command. It acts like a regular mapping but also has a convenience method get which can return data in the appropriate type.

For instance this can be used to query the server for the role it’s in (master, slave) etc:

let info : redis::InfoDict = redis::cmd("INFO").query(&mut con)?;
let role : Option<String> = info.get("role");

Creates a new info dictionary from a string in the response of the INFO command. Each line is a key, value pair with the key and value separated by a colon (:). Lines starting with a hash (#) are ignored.

Fetches a value by key and converts it into the given type. Typical types are String, bool and integer types.

Looks up a key in the info dict.

Checks if a key is contained in the info dicf.

Returns the size of the info dict.

Checks if the dict is empty.

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
