Type::Params::Alternatives - subclass of Type::Params::Signature for "multi" signatures

This module is not covered by the Type-Tiny stability policy.

This is mostly internal code, but can be used to provide basic introspection for signatures.

This module is a subclass of Type::Parameters::Signature, so inherits attributes and methods from that.

All attributes are read-only.

"base_options" HashRef
"alternatives" ArrayRef[HashRef|ArrayRef|CodeRef]
"sig_class" ClassName
"meta_alternatives" ArrayRef[HashRef]
Automatically built from "alternatives"; do not set this yourself.
"parameters" ArrayRef
Overridden from parent class to always return the empty arrayref.
"message" Str
Error message to be thrown when none of the alternatives match. This is a bare attribute with no accessor method.

Please report any bugs to https://github.com/tobyink/p5-type-tiny/issues.

Type::Params, Type::Params::Signature.
