Struct Fsync

pub struct Fsync { /* private fields */ }

File sync. See also fsync (2).

Note that, while I/O is initiated in the order in which it appears in the submission queue, completions are unordered. For example, an application which places a write I/O followed by an fsync in the submission queue cannot expect the fsync to apply to the write. The two operations execute in parallel, so the fsync may complete before the write is issued to the storage. The same is also true for previously issued writes that have not completed prior to the fsync.

Implementations

impl Fsync

pub const fn new(fd: Target) -> Self

pub const fn flags(self, flags: FsyncFlags) -> Self

The flags bit mask may contain either 0, for a normal file integrity sync, or types::FsyncFlags::DATASYNC to provide data sync only semantics. See the descriptions of O_SYNC and O_DSYNC in the open (2) manual page for more information.

pub fn build(self) -> Entry

Trait Implementations

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
