Expand description
Macro for generically accessing a FFI static
The expected arguments are, in order:
- (Optional) The name of the cargo feature conditioning the usage of dlopen, in the form
feature="feature-name"
. If ommited, the feature"dlopen"
will be used. - A value of the handle generated by the macro
external_library!
when the dlopen-controlling feature is enabled - The name of the static
The macro invocation evaluates to a &T
reference to the static
§Example
ⓘ
let my_static = unsafe { ffi_dispatch!(feature="dlopen", LIBRARY_HANDLE, my_static) };
