Struct OpenOptions

pub struct OpenOptions { /* private fields */ }

Options and flags which can be used to configure how a file is opened.

This builder exposes the ability to configure how a File is opened and what operations are permitted on the open file. The File::open and File::create methods are aliases for commonly used options using this builder.

Generally speaking, when using OpenOptions, you’ll first call OpenOptions::new, then chain calls to methods to set each option, then call OpenOptions::open, passing the path of the file you’re trying to open. This will give you a io::Result with a File inside that you can further operate on.

Examples

Opening a file to read:

use tokio_uring::fs::OpenOptions;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    tokio_uring::start(async {
        let file = OpenOptions::new()
            .read(true)
            .open("foo.txt")
            .await?;
