On: The Case for Writing a Kernel in Rust [pdf]

[oconnor663]

There are safe interfaces for this stuff too. The byteorder crate (not in the standard library, but widely used) has:

    let i = NativeEndian::read_i64(...);

Or if you're literally parsing a string of digits:

    let i: Option<i64> = digits.parse();

The `parse` method on strings is a particularly smooth piece of trait system magic.
