Struct WriteOptions

pub struct WriteOptions {
    pub synchronous: bool,
}

Options for write operations.

Fields

synchronous: bool

Whether or not to perform the write operation synchronously.

If true, the program will try to ensure that the write is flusehd completely to disk before it considers the write complete. This extra check means that writes with this flag on will be slower.

If false and the machine crashes, some recent writes might be lost. Note that, if it is just the program that crashes (i.e. the machine does not reboot), then no writes will be lost.

In other words, writes with this flag false has the same semantics as just a write() system call. A write with the flag as true has the semantics of a write() followed by an fsync().

Defaults to false.
