Hash.try_convert

[U, V] (::_ToHash[U, V]) -> ::Hash[U, V]

(untyped) -> (::Hash[untyped, untyped] | nil)

Hash.try_convert(object) → object, new_hash, or nil

static VALUE
rb_hash_s_try_convert(VALUE dummy, VALUE hash)
{
    return rb_check_hash_type(hash);
}

If object is a hash, returns object.

Otherwise if object responds to :to_hash, calls object.to_hash; returns the result if it is a hash, or raises TypeError if not.

Otherwise if object does not respond to :to_hash, returns nil.
