Source

pub fn unit(&self) -> TypeVariable

Source

pub fn int(&self) -> TypeVariable

Source

pub fn error_recovery(&mut self, err: TypeError) -> TypeVariable

To reference an error recovery type, you must provide an error. This holds the invariant that error recovery types are only generated when an error occurs.
