Each type constraint knows how to generate a string of Perl code for validating a value, given a variable name for the value.

For example:

$ perl -MDevel::Hide=Ref::Util::XS,Type::Tiny::XS -MTypes::Standard=-t
+ypes -E'say HashRef->inline_check(q/$myvar/)'
Devel::Hide hides Ref/Util/XS.pm, Type/Tiny/XS.pm
(ref($myvar) eq 'HASH')

So the ArrayRef[HashRef] type constraint can use that when generating a longer bit of code to validate an arrayref of hashrefs:

$ perl -MDevel::Hide=Ref::Util::XS,Type::Tiny::XS -MTypes::Standard=-t
+ypes -E'say ArrayRef->of(HashRef)->inline_check(q/$myvar/)'
Devel::Hide hides Ref/Util/XS.pm, Type/Tiny/XS.pm
do { (ref($myvar) eq 'ARRAY') and do { my $ok = 1; for my $i (@{$myvar
+}) { ($ok = 0, last) unless (ref($i) eq 'HASH') }; $ok } }
