Crate vmm_sys_util

Collection of modules that provides helpers and utilities used by multiple rust-vmm components.

Modules

aioLinux or Android

Safe wrapper over Linux AIO.

align

Miscellaneous macros related to align addresses

epollLinux or Android

Safe wrappers over the epoll API.

errno

Structures, helpers, and type definitions for working with errno.

eventfdLinux or Android

Structure and wrapper functions for working with eventfd.

fallocateLinux or Android

Enum and function for dealing with an allocated disk space by fallocate.

fam
