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

Checks if this channel is "stable".

fn is_nightly(self) -> bool

Checks if this channel is "nightly".

fn is_beta(self) -> bool

Checks if this channel is "beta".

fn is_beta_num(self, n: u8) -> bool

Checks if this channel is "beta.n".

fn as_type_str(self) -> &'static str

A string for the type of channel, i.e. stable, beta, or nightly.

fn rustup_update(&self) -> Result<()>

Updates this channel via rustup.

fn comparable(self) -> OrdChannel

Creates an Ord version of this Channel, usually for testing.

Trait Implementations

impl Debug for Channel

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Clone for Channel

fn clone(&self) -> Channel

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Channel

impl PartialEq for Channel

fn eq(&self, __arg_0: &Channel) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &Channel) -> bool

This method tests for !=.

impl PartialOrd for Channel

fn partial_cmp(&self, __arg_0: &Channel) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, __arg_0: &Channel) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, __arg_0: &Channel) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, __arg_0: &Channel) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, __arg_0: &Channel) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Display for Channel

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl From<BetaNum> for Channel

fn from(beta: BetaNum) -> Channel

Performs the conversion.

impl PartialEq<OrdChannel> for Channel

fn eq(&self, rhs: &OrdChannel) -> bool

This method tests for self and other values to be equal, and is used by ==.
