Enum extendr_api::prelude::modules::core::Parallelism
#[non_exhaustive]pub enum Parallelism<'a> {
None,
Rayon(usize),
}
Expand description
Parallelism strategy that can be passed to most of the routines in the library.
Variants (Non-exhaustive)§
This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
None
No parallelism.
The code is executed sequentially on the same thread that calls a function and passes this argument.
Rayon(usize)
Rayon parallelism. Only available with the rayon
feature.
The code is possibly executed in parallel on the current thread, as well as the currently active rayon thread pool.
The contained value represents a hint about the number of threads an implementation should use, but there is no way to guarantee how many or which threads will be used.
A value of 0
treated as equivalent to rayon::current_num_threads()
.
