DESCRIPTION

    This is an experimental module to ease validating function arguments
    for unwrapped function.

FUNCTIONS

    All the functions are exported by default.

 validate_args(\%args) => $err

    Get Rinci function metadata from caller's %SPEC package variable. Then
    create (and cache) a set of Data::Sah validator to check the value of
    each argument. If there is an error, will return an error response
    $err. Otherwise will return undef.

    Arguments in %args will have their default values/coercions/filters
    applied, so they are ready for use.

    Currently only support args_as => 'hash' (the default).
