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

Modules

aio

Safe wrapper over Linux AIO.

epoll

Safe wrappers over the epoll API.

errno

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

eventfd

Structure and wrapper functions for working with eventfd.

fallocate

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

fam

Trait and wrapper for working with C defined FAM structures.

file_traits

Traits for handling file synchronization and length.
