Sync

Synchronization primitives to build concurrent-safe and parallel-safe data structures, so we can embrace concurrency and parallelism with more serenity.

Communication through a Channel should be preferred whenever possible, but sometimes we need to protect critical sections manually, for example to build higher level constructs, or to protect a mutable global constant:

• Sync::Mutex to protect critical sections using mutual exclusion.
• Sync::RWLock to protect critical sections using shared access and mutual exclusion.
• Sync::ConditionVariable to synchronize critical sections together.
• Sync::Exclusive(T) to protect a value T using mutual exclusion.
• Sync::Shared(T) to protect a value T using a mix of shared access and mutual exclusion.
