Function renamore::rename_exclusive_fallback

pub fn rename_exclusive_fallback<F: AsRef<Path>, T: AsRef<Path>>(
    from: F,
    to: T
) -> Result<bool>

Rename a file without overwriting the destination path if it exists, using a non-atomic fallback if necessary.

This is similar to rename_exclusive except that if performing the operation atomically is not supported, then a non-atomic fallback implementation based on try_exists and rename will be used.

Examples

if renamore::rename_exclusive_fallback("old.txt", "new.txt")? {
    // `new.txt` was definitely not overwritten.
    println!("The operation was atomic");
} else {
    // `new.txt` was probably not overwritten.
    println!("The operation was not atomic");
}
