1///A builder struct for commands where you set multiple values at once. It utilizes
2///references to ensure that it does not copy any of the data given to it. It supports
3///the classic builder-pattern, as well as a mutable pattern.
4///# Example
5///```
6///# use darkredis::MSetBuilder;
7/// //Builder-style
8///let mut builder = MSetBuilder::new().set(b"example-key", b"some-value");
9///
10/// // Mutable style
11///builder.append(b"some-other-key", b"some-value");
12///```
