List::Objects::WithUtils::Array::Typed - Type-checking array objects
use List::Objects::WithUtils 'array_of'; use Types::Standard -all; use List::Objects::Types -all; my $arr = array_of( Int() => 1 .. 10 ); $arr->push('foo'); # dies, failed type check $arr->push(11 .. 15); # ok my $arr_of_arrs = array_of( ArrayObj ); $arr_of_arrs->push([], []); # ok, coerces to ArrayObj
These are type-checking array objects; elements are checked against the specified type when the object is constructed or new elements are added.
The first argument passed to the constructor should be a Type::Tiny type:
use Types::Standard -all; my $arr = array_of Str() => qw/foo bar baz/;
If the initial type-check fails, a coercion is attempted.
