Function extendr_api::thread_safety::single_threaded
source · pub fn single_threaded<F, R>(f: F) -> Rwhere
F: FnOnce() -> R,
Expand description
Run f
while ensuring that f
runs in a single-threaded manner.
This is intended for single-threaded access of the R’s C-API.
It is possible to have nested calls of single_threaded
without deadlocking.
Note: This will fail badly if the called function f
panics or calls Rf_error
.
