List::Objects::WithUtils::Hash::Typed - Type-checking hash objects
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 module requires Type::Tie.
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.
It's worth noting that this comes with the obvious type-checking performance hit, plus some extra overhead.
Returns the Type::Tiny type the object was created with.
