Struct cargo::core::compiler::job_queue::JobQueue

pub struct JobQueue<'gctx> {
    queue: DependencyQueue<Unit, Artifact, Job>,
    counts: HashMap<PackageId, usize>,
    timings: Timings<'gctx>,
}

This structure is backed by the DependencyQueue type and manages the queueing of compilation steps for each package. Packages enqueue units of work and then later on the entire graph is converted to DrainState and executed.

Fields

queue: DependencyQueue<Unit, Artifact, Job>

counts: HashMap<PackageId, usize>

timings: Timings<'gctx>

Implementations

impl<'gctx> JobQueue<'gctx>

pub fn new(bcx: &BuildContext<'_, 'gctx>) -> JobQueue<'gctx>

pub fn enqueue( &mut self, build_runner: &BuildRunner<'_, 'gctx>, unit: &Unit, job: Job, ) -> CargoResult<()>

pub fn execute( self, build_runner: &mut BuildRunner<'_, '_>, plan: &mut BuildPlan, ) -> CargoResult<()>

Executes all jobs necessary to build the dependency graph.

This function will spawn off config.jobs() workers to build all of the necessary dependencies, in order. Freshness is propagated as far as possible along each dependency chain.

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.
