If a new file is created as part of an OpenOptions::open call then this
specified mode will be used as the permission bits for the new file.
If no mode is set, the default of 0o666 will be used.
The operating system masks out bits with the system’s umask, to produce
the final permissions.
Examples
use std::fs::OpenOptions; use std::os::unix::fs::OpenOptionsExt; let mut options = OpenOptions::new(); options.mode(0o644); // Give read/write for owner and read for others. let file = options.open("foo.txt");Run

The bits that define the access mode are masked out with O_ACCMODE, to
ensure they do not interfere with the access mode set by Rusts options.
Custom flags can only set flags, not remove flags set by Rusts options. This options overwrites any previously set custom flags.
Examples
extern crate libc; use std::fs::OpenOptions; use std::os::unix::fs::OpenOptionsExt; let mut options = OpenOptions::new(); options.write(true); if cfg!(unix) { options.custom_flags(libc::O_NOFOLLOW); } let file = options.open("foo.txt");Run
