Struct CyclicStep

pub struct CyclicStep {
    n: u32,
}

Dummy step that can be used to deliberately trigger bootstrap’s step cycle detector, for automated and manual testing.

Fields

n: u32

Trait Implementations

impl Clone for CyclicStep

fn clone(&self) -> CyclicStep

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CyclicStep

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

Formats the value using the given formatter.

impl Hash for CyclicStep

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for CyclicStep

fn eq(&self, other: &CyclicStep) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Step for CyclicStep

type Output = ()

Result type of Step::run.

fn should_run(run: ShouldRun<'_>) -> ShouldRun<'_>

Determines if this Step should be run when given specific paths (e.g., x build $path).

fn make_run(run: RunConfig<'_>)

Called directly by the bootstrap Step handler when not triggered indirectly by other Steps using Builder::ensure. For example, ./x.py test bootstrap runs this for test::Bootstrap. Similarly, ./x.py test runs it for every step that is listed by the describe macro in Builder::get_step_descriptions.

fn run(self, builder: &Builder<'_>) -> Self::Output

Primary function to implement Step logic.

const DEFAULT: bool = false

Whether this step is run by default as part of its respective phase, as defined by the describe macro in Builder::get_step_descriptions.

const ONLY_HOSTS: bool = false

If true, then this rule should be skipped if –target was specified, but –host was not

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
