Function lagoon::available_concurrency

pub fn available_concurrency() -> Option<usize>

Attempt to determine the available concurrency of the host system.

In most cases, this corresponds to the number of CPU cores that are available to the program. If the num_cpus feature is enabled (it is by default) the num_cpus crate will be used to determine this value. Otherwise, the nightly-only std::thread::available_concurrency function will be used.
