Crate nix 

Rust friendly bindings to the various *nix system functions.

Modules are structured according to the C header file that they would be defined in.

Features

Nix uses the following Cargo features to enable optional functionality. They may be enabled in any combination.

• acct - Process accounting
• aio - POSIX AIO
• dir - Stuff relating to directory iteration
• env - Manipulate environment variables
• event - Event-driven APIs, like kqueue and epoll
• fanotify - Linux’s fanotify filesystem events monitoring API
• feature - Query characteristics of the OS at runtime
• fs - File system functionality
• hostname - Get and set the system’s hostname
• inotify - Linux’s inotify file system notification API
• ioctl - The ioctl syscall, and wrappers for many specific instances
• kmod - Load and unload kernel modules
• mman - Stuff relating to memory management
• mount - Mount and unmount file systems
• mqueue - POSIX message queues
• net - Networking-related functionality
• personality - Set the process execution domain
• poll - APIs like poll and select
• process - Stuff relating to running processes
• pthread - POSIX threads
• ptrace - Process tracing and debugging
• quota - File system quotas
• reboot - Reboot the system
• resource - Process resource limits
• sched - Manipulate process’s scheduling
• socket - Sockets, whether for networking or local use
• signal - Send and receive signals to processes
• syslog - System logging
• term - Terminal control APIs
• time - Query the operating system’s clocks
• ucontext - User thread context
• uio - Vectored I/O
• user - Stuff relating to users and groups
• zerocopy - APIs like sendfile and copy_file_range
