Crate vmm_sys_util

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.
• ioctl
  Macros and functions for working with ioctl.
• metric
  The purpose of this module is to provide abstractions for working with metrics in the context of rust-vmm components where there is a strong need to have metrics as an optional feature.
• poll
  Traits and structures for working with epoll
• rand
  Miscellaneous functions related to getting (pseudo) random numbers and strings.
• seek_hole
  Traits and implementations over lseek64.
• signal
  Enums, traits and functions for working with signal.
• sock_ctrl_msg
  Wrapper for sending and receiving messages with file descriptors on sockets that accept control messages (e.g. Unix domain sockets).
• syscall
  Wrapper for interpreting syscall exit codes.
• tempdir
  Structure for handling temporary directories.
• tempfile
  Struct for handling temporary files as well as any cleanup required.
• terminal
  Trait for working with termios.
• timerfd
  Structure and functions for working with timerfd.
• write_zeroes
  Traits for replacing a range with a hole and writing zeroes in a file.

Macros

• generate_fam_struct_impl
  Generate FamStruct implementation for structs with flexible array member.
• ioctl_io_nr
  Declare an ioctl that transfers no data.
• ioctl_ioc_nr
  Declare a function that returns an ioctl number.
• ioctl_ior_nr
  Declare an ioctl that reads data.
• ioctl_iow_nr
  Declare an ioctl that writes data.
• ioctl_iowr_nr
