literal | Literal uses code generation at startup

literal is a Ruby library. literal has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

The performance impact of most of the types is negligible: a single case equality check against the given type. Some of the advanced collection types, such as _Array and _Hash could be pretty bad for performance, since they need to check every value at runtime. The idea here is to disable these type checks in production, though I must confess, haven’t built the switch for that just yet. The first tool we provide is the Literal::Attributes mixin. It allows you to define type-checked attribute accessors. By default, writers are private and readers are not defined. It also provides a default initializer which assigns all the keyword arguments to the corresponding attributes. This is done through the attribute writers, so the types are checked. Here we have a user class with a name and an age. The name is a String and the age is between 18 and infinity.
