Function cacache::reflink_sync

source ·

pub fn reflink_sync<P, K, Q>(cache: P, key: K, to: Q) -> Result<()>where
    P: AsRef<Path>,
    K: AsRef<str>,
    Q: AsRef<Path>,

Expand description

Creates a reflink/clonefile from a cache entry to a destination path.

Fails if the destination is on a different filesystem or if the filesystem does not support reflinks.

Currently, reflinks are known to work on APFS (macOS), XFS, btrfs, and ReFS (Windows DevDrive)

§Example

use async_std::prelude::*;
use async_attributes;

#[async_attributes::main]
async fn main() -> cacache::Result<()> {
    cacache::reflink_sync("./my-cache", "my-key", "./data.txt")?;
    Ok(())
}
