Struct rust_version::BetaNum
[−]
[src]
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
[src]
fn new(n: u8) -> BetaNum
[src]
Creates a beta with a version number.
If zero is given, this is equivalent to BetaNum::ambiguous()
.
fn ambiguous() -> BetaNum
[src]
Creates a beta without a version number.
fn num(self) -> Option<u8>
[src]
Gets the version for this beta, if given.
