This PR implements AsyncReadRent and AsyncWriteRent for File, completing the following tasks:
op::read<T>
andop::write<T>
to support reading/writing files using the file pointer.OVERLAPPED
struct to reduce the number of syscalls.readv
andwritev
would always start from the beginning of the file.readv
andwritev
on Windows.readv
andwritev
by continually calling theread
andwrite
functions.AsyncWriteRent
andAsyncReadRent
.readv/writev
-like syscalls on the Windows platform, the structure ofsrc/fs/file.rs
was changed for better readability of the implementations on different platforms.Other details are shown in the code.
