is_raw(x, .xname = get_name_in_parent(x))

Arguments

x	Input to check.
severity	How severe should the consequences of the assertion be? Either "stop", "warning", "message", or "none".
.xname	Not intended to be used directly.

Value

is_raw wraps is.raw, providing more information on failure. is_a_raw returns TRUE if the input is raw and scalar. The assert_* functions return nothing but throws an error if the corresponding is_* function returns FALSE.
