Provided Associated Constants§

Source

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.

Note: Even if set to true, it can still be overridden with ShouldRun::default_condition by Step::should_run.

Source

const ONLY_HOSTS: bool = false

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

Required Associated Types§

Source

type Output: Clone

Result type of Step::run.

Required Methods§

Source

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

Primary function to implement Step logic.

This function can be triggered in two ways: 1. Directly from Builder::execute_cli. 2. Indirectly by being called from other Steps using Builder::ensure.

When called with Builder::execute_cli (as done by Build::build), this function executed twice: - First in “dry-run” mode to validate certain things (like cyclic Step invocations, directory creation, etc) super quickly. - Then it’s called again to run the actual, very expensive process.

When triggered indirectly from other Steps, it may still run twice (as dry-run and real mode) depending on the Step::run implementation of the caller.

Source

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

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

Provided Methods§

Source

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.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
