This function extracts the exports from the namespace of the given package
via getNamespaceExports and discards non-fuzzable objects (non-functions
and functions with no arguments). The set of names returned can be further
restricted via the ignore_names
argument.
Value
A character vector of the names of the fuzzable functions exported from
the given package, with the "package"
attribute set. This can be used
directly as the funs
argument of fuzz without need to specify the
package
argument.
