fn into_inner(self) -> Result<(Format, Self::Options), Self::Error>

Closes this FileManager, returning the Format and Options parameters used to construct it.

fn create_overwrite<P: AsRef<Path>>( path: P, format: Self::Format, options: Self::Options, value: T, ) -> Result<(T, Self), Self::Error>

Open a new instance of this FileManager, creating a file at the given path if it does not exist, and overwriting its contents if it does.
