Currently in Rust's std there are 2 functions that read directly the content of a file:

fn read<P: AsRef<Path>>(path: P) -> Result<Vec<u8>>

and

fn read_to_string<P: AsRef<Path>>(path: P) -> Result<String>

the question that I ask myself is, why isn't there a trait (e.g. FromRead / Readable, ...) that could allow to do this:

fn read<P: AsRef<Path>, T: FromRead>(path: P) -> Result<T>

Was that ever thought when designing std::fs ? If so, what are the arguments against it ?
