If the specified path isn't a directory, fail.

Implicitly follow each write()
with an fdatasync()
.
pub const O_EXCL: OFlag
O_EXCL: OFlag = OFlag{bits: libc::O_EXCL,}
Error out if a file was not created.
pub const O_FSYNC: OFlag
O_FSYNC: OFlag = OFlag{bits: libc::O_FSYNC,}
Same as O_SYNC
.
pub const O_LARGEFILE: OFlag
O_LARGEFILE: OFlag = OFlag{bits: libc::O_LARGEFILE,}

open()
will fail if the given path is a symbolic link.

Similar to O_DSYNC
but applies to read
s instead.

with an fsync()
.

Create an unnamed temporary file.
pub const O_TRUNC: OFlag
O_TRUNC: OFlag = OFlag{bits: libc::O_TRUNC,}

Returns true
if no flags are currently stored.

pub fn is_all(&self) -> bool
Returns true

if there are flags common to both self
and other
.

.
