class RakuAST::Type::Coercion

class RakuAST::Type::Coercion { }

The RakuAST::Type::Coercion class represents a Raku type that coerces.

Object introspection§

RakuAST::Type::Coercion object is typically created when parsing Raku Programming Language code. So most developers will only need to know how to introspect the objects created.

base-type§

dd $type.base-type;  # Int

The base-type method returns the RakuAST::Type object that was specified with the "base-type" named argument in the call to .new.

constraint§

dd $type.constraint;  # Str

The constraint method returns the RakuAST::Type object that was specified with the "constraint" named argument in the call to .new.

is-coercive§

say $type.is-coercive;  # True

The is-coercive method always returns True.

Object creation§

There is only one way to create a RakuAST::Type::Coercion object.

new§

my $type = RakuAST::Type::Coercion.new(
  base-type  => RakuAST::Type::Simple.from-identifier("Int"),
  constraint => RakuAST::Type::Simple.from-identifier("Str")
);
dd $type;  # Int(Str)

The .new method creates a RakuAST::Type::Coercion object. It expects the following named arguments:

• :base-type - RakuAST::Type object for the base type (required)
• :constraint - RakuAST::Type object (optional, default: Any)
