Macro assert_debug_snapshot

macro_rules! assert_debug_snapshot {
    ($value:expr, @$snapshot:literal) => { ... };
    ($name:expr, $value:expr) => { ... };

}

Asserts a Debug snapshot.

The value needs to implement the fmt::Debug trait. This is useful for simple values that do not implement the Serialize trait but does not permit redactions.

Debug is called with "{:#?}", which means this uses pretty-print.

The snapshot name is optional.
