List::Objects::WithUtils::Role::Hash::Typed - Type-checking hash behavior
# Via List::Objects::WithUtils::Hash::Typed -> use List::Objects::WithUtils 'hash_of'; use Types::Standard -all; my $arr = hash_of(Int, foo => 1, bar => 2); $arr->set(baz => 3.14159); # dies, failed type check
This role makes use of Type::Tie to add type-checking behavior to List::Objects::WithUtils::Role::Hash consumers.
The first argument passed to the constructor should be a Type::Tiny type:
use Types::Standard -all; my $arr = hash_of ArrayRef() => (foo => [], bar => []);
Values are checked against the specified type when the object is constructed or new elements are added.
If the initial type-check fails, a coercion is attempted.
Values that cannot be coerced will throw an exception.
Also see Types::Standard, List::Objects::Types
Returns the Type::Tiny type the object was created with.
Returns a (shallow) clone that is a plain List::Objects::WithUtils::Hash.
