Enum rust_version::Channel

pub enum Channel {
    Stable,
    Beta(BetaNum),
    Nightly,
}

Rust version channel.

Channels only implement PartialEq and PartialOrd because betas can't be fully compared. See BetaNum for more information.

Variants

Stable

Stable build.

Beta(BetaNum)

Beta build.

Nightly

Nightly build.

Methods

impl Channel

fn is_stable(self) -> bool
