Crate linux_aio_tokio

Tokio Bindings for Linux Kernel AIO

This package provides an integration of Linux kernel-level asynchronous I/O to the Tokio platform.

Linux kernel-level asynchronous I/O is different from the Posix AIO library. Posix AIO is implemented using a pool of userland threads, which invoke regular, blocking system calls to perform file I/O. Linux kernel-level AIO, on the other hand, provides kernel-level asynchronous scheduling of I/O operations to the underlying block device.

Structs

AioContext	Represents running AIO context. Must be kept while AIO is in use. In order to close it, close should be called. It will wait until all related futures are finished. Otherwise, if it just dropped, the termination will be triggered, but some running futures will continue running until they receive the data.
AioContextHandle	Cloneable handle to AIO context. Required for any AIO operations
EventFd	Tokio-aware EventFd implementation
File	AIO version of tokio File, to work through AioContextHandle
LockedBuf	Buffer with fixed capacity, locked to RAM. It prevents memory from being paged to the swap area
RawCommand	Raw AIO command
ReadFlags	AIO read flags. See io_submit
WriteFlags	AIO write flags. See io_submit

Enums

AioCommandError	AIO command error
AioContextError	AIO context creation error
LockedBufError	Error during LockedBuf creation
Opcode	Represents AIO operation. See io_submit
