Build Values from a JSON-like notation

This macro handles:

• u8, u16, u32, i8, i16, i32, i64, String, &str and other types that implement IntoRedisValue
• true, false - map to their corresponding Value::Boolean
• nil - maps to Value::Nil
• ok, okay - map to Value::Okay
• [element1, element2, ..., elementN] - maps to Value::Array
• {key1: value1, key2: value2, ..., keyN: valueN] - maps to Value::Map
• set:[element1, element2, ..., elementN] - maps to Value::Set (wrap in () within complex structures)
• simple:"SomeString" - maps to Value::SimpleString (wrap in () within complex structures)

Example

use redis::Value;
use redis_test::redis_value;

let actual = redis_value!([42, "foo", {true: nil}]);

let expected = Value::Array(vec![
  Value::Int(42),
  Value::BulkString("foo".as_bytes().to_vec()),
  Value::Map(vec![(Value::Boolean(true), Value::Nil)])
]);
assert_eq!(actual, expected)
