Struct rust_version::BetaNum

pub struct BetaNum(_);

Version for a Rust beta. This is either "beta" or "beta.N", where N is an integer.

Beta versions only implement PartialEq and PartialOrd because betas which don't have a version are not comparable to other beta versions.

Methods

impl BetaNum

fn new(n: u8) -> BetaNum

Creates a beta with a version number.

If zero is given, this is equivalent to BetaNum::ambiguous().

fn ambiguous() -> BetaNum

Creates a beta without a version number.

fn num(self) -> Option<u8>

Gets the version for this beta, if given.
