Module ffi_utils::test_utils[−][src]

Test utilities.

Structs

SendWrapper	Unsafe wrapper for passing non-Send types through mpsc channels. Use with caution!
UserData	User data wrapper.

Functions

call_0	Call a FFI function and block until its callback gets called. Use this if the callback accepts no arguments in addition to `user_data` and `error_code`.
call_1 ^⚠	Call an FFI function and block until its callback gets called, then return the argument which were passed to that callback. Use this if the callback accepts one argument in addition to `user_data` and `error_code`.
call_2 ^⚠	Call a FFI function and block until its callback gets called, then return the argument which were passed to that callback. Use this if the callback accepts two arguments in addition to `user_data` and `error_code`.
call_0_with_custom	Call a FFI function and block until its callback gets called. Use this if the callback accepts no arguments in addition to `user_data` and `error_code`. This version of the function takes a `UserData` with custom inner data.
call_1_with_custom	Call an FFI function and block until its callback gets called, then return the argument which were passed to that callback. Use this if the callback accepts one argument in addition to `user_data` and `error_code`. This version of the function takes a `UserData` with custom inner data.
call_2_with_custom ^⚠	Call a FFI function and block until its callback gets called, then return the argument which were passed to that callback. Use this if the callback accepts two arguments in addition to `user_data` and `error_code`. This version of the function takes a `UserData` with custom inner data.
call_vec ^⚠	Call a FFI function and block until its callback gets called, then copy the array argument which was passed to `Vec<T>` and return the result. Use this if the callback accepts `*const T` and `usize` (length) arguments in addition to `user_data` and `error_code`.
call_vec_u8 ^⚠	Call a FFI function and block until its callback gets called, then copy the byte array argument which was passed to `Vec<u8>` and return the result.
call_vec_u8_with_custom ^⚠	Call a FFI function and block until its callback gets called, then copy the byte array argument which was passed to `Vec<u8>` and return the result. This version of the function takes a `UserData` with custom inner data. This version of the function takes a `UserData` with custom inner data.
call_vec_with_custom ^⚠	Call a FFI function and block until its callback gets called, then copy the array argument which was passed to `Vec<T>` and return the result. Use this if the callback accepts `*const T` and `usize` (length) arguments in addition to `user_data` and `error_code`. This version of the function takes a `UserData` with custom inner data.
send_via_user_data ^⚠	Send through a `mpsc::Sender` pointed to by the user data's common pointer.
send_via_user_data_custom ^⚠	Send through a `mpsc::Sender` pointed to by the user data's custom pointer.
sender_as_user_data	Convert a `mpsc::Sender<T>` to a void ptr which is then stored in the `UserData` struct and passed to ffi functions.
user_data_as_void	Convert a `UserData` to a void pointer which can be passed to ffi functions.
