Struct bootstrap::core::build_steps::test::Coverage

pub struct Coverage {
    pub compiler: Compiler,
    pub target: TargetSelection,
}

Coverage tests are a bit more complicated than other test suites, because we want to run the same set of test files in multiple different modes, in a way that’s convenient and flexible when invoked manually.

This combined step runs the specified tests (or all of tests/coverage) in both “coverage-map” and “coverage-run” modes.

Used by:

• x test coverage
• x test tests/coverage
• x test tests/coverage/trivial.rs (etc)

(Each individual mode also has its own step that will run the tests in just that mode.)

Fields

compiler: Compiler

target: TargetSelection

Implementations

impl Coverage

const PATH: &'static str = "tests/coverage"

const SUITE: &'static str = "coverage"

fn run_coverage_tests( builder: &Builder<'_>, compiler: Compiler, target: TargetSelection, mode: &'static str )

Runs the coverage test suite (or a user-specified subset) in one mode.

This same function is used by the multi-mode step (Coverage) and by the single-mode steps (CoverageMap and CoverageRun), to help ensure that they all behave consistently with each other, regardless of how the coverage tests have been invoked.

Trait Implementations

impl Clone for Coverage

fn clone(&self) -> Coverage

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Coverage

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

Formats the value using the given formatter.

impl Hash for Coverage

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 Coverage

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

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

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

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

impl Step for Coverage

const DEFAULT: bool = false

We rely on the individual CoverageMap/CoverageRun steps to run themselves.

const ONLY_HOSTS: bool = false

When manually invoked, try to run as much as possible. Compiletest will automatically skip the “coverage-run” tests if necessary.

type Output = ()

PathBuf when directories are created or to return a Compiler once it’s been assembled.

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

When bootstrap is passed a set of paths, this controls whether this rule will execute. However, it does not get called in a “default” context when we are not passed any paths; in that case, make_run is called directly.

fn make_run(run: RunConfig<'_>)

Builds up a “root” rule, either as a default rule or from a path passed to us.

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

Primary function to execute this rule. Can call builder.ensure() with other steps to run those.

impl Eq for Coverage

impl StructuralPartialEq for Coverage

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.
