Struct CachedRuntimePackages 

pub struct CachedRuntimePackages { /* private fields */ }

Production package adapter. It takes an e2 lease before returning, so a cache entry can never look unused while its runtime is starting.

Implementations

impl CachedRuntimePackages

pub const fn new(cache: Arc<PackageCache>, shared: SharedPackages) -> Self

One target’s view of the package directory the targets of shared use.

Trait Implementations

impl Debug for CachedRuntimePackages

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

Formats the value using the given formatter.

impl RuntimePackages for CachedRuntimePackages

fn prune_obsolete_guarded( &self, _authority: PruneAuthority<'_>, attempts: &[RunnerAttempt], ) -> Result<(), FailureReason>

Everything but the newest version, when nothing is using the trees: a copy from an older version, or an install in progress, makes this a no-op, and a later launch prunes what it left, which costs only disk.

fn materialize<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, attempt: &'life1 RunnerAttempt, timings: &'life2 mut PackageTimings, ) -> Pin<Box<dyn Future<Output = Result<RunnerVersion, FailureReason>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Copy the package into attempt’s runtime, adding where the time went to timings.

fn release(&self, attempt: AttemptId) -> Result<(), FailureReason>
