Abstract the state type for futexes

2024-10-17T19:21:53+00:00

In the same way that we expose SmallAtomic and SmallPrimitive to allow Windows to use a value other than an AtomicU32 for its futex state, this patch switches the primary futex state type from AtomicU32 to futex::Atomic. The futex::Atomic type should be usable as an atomic value with underlying primitive type equal to futex::Primitive. This allows supporting the futex API on systems where the underlying kernel futex implementation requires more state than simply an AtomicU32. All in-tree futex implementations simply define {Atomic,Primitive} directly as {AtomicU32,u32}.

add HermitOS support of vectored read/write operations

2024-06-07T18:48:30+00:00

In general, the I/O interface of hermit-abi is more POSIX-like interface. Consequently, platform abstraction layer for HermitOS has slightly adjusted and some inaccuracies remove.

increase the readability by using the unique name for the hermit-abi

Take up suggestion from the discussions within rust-lang/rust#115984 to increase readability.
