Enum CoverageModeAlias 

pub enum CoverageModeAlias {}

Registers the coverage-map and coverage-run aliases, which are then forwarded to the Coverage step.

If the aliases were registered by Coverage directly, they would also be treated as implied command-line arguments when run by default. That would cause things like ./x test --skip=tests to still run coverage tests, which is undesirable.

Trait Implementations

impl Clone for CoverageModeAlias

fn clone(&self) -> CoverageModeAlias

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl CommandLineStep for CoverageModeAlias

type Output = ()

Result type of Step::run.

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

Called to allow steps to register the command-line paths that should cause them to run.

fn is_default_step(_builder: &Builder<'_>) -> bool

Should this step run when the user invokes bootstrap with a subcommand but no paths/aliases?

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<'_>)

Used as the implementation of Step::run.

const IS_HOST: bool = false

If this value is true, then the values of run.target passed to the make_run function of this Step will be determined based on the --host flag. If this value is false, then they will be determined based on the --target flag.

fn metadata(&self) -> Option<StepMetadata>

Used as the implementation of Step::metadata.

impl Debug for CoverageModeAlias

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

Formats the value using the given formatter.

impl Eq for CoverageModeAlias

impl Hash for CoverageModeAlias

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 CoverageModeAlias

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

Equality operator ==.

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

Inequality operator !=.

impl StructuralPartialEq for CoverageModeAlias

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.
