Allowlisting allows us to be precise about which type, function, and global variable definitions bindgen
generates bindings for. By default, if we don't specify any allowlisting rules, everything is considered allowlisted. This may not be desirable because of either
If we specify allowlisting rules, then bindgen
will only generate bindings to types, functions, and global variables that match the allowlisting rules, or are transitively used by a definition that matches them.
--allowlist-type <type>
--allowlist-function <function>
--allowlist-var <var>
None.
