Member Function Documentation

jobCategory()

virtual JobCategory nix::Goal::jobCategory ( ) const

pure virtual

Hint for the scheduler, which concurrency limit applies.

JobCategory

Implemented in nix::DerivationGoal, nix::DrvOutputSubstitutionGoal, and nix::PathSubstitutionGoal.

Member Data Documentation

isDependency

const bool nix::Goal::isDependency

Whether this goal is only a dependency of other goals. Toplevel goals that are also dependencies of other toplevel goals do not set this, only goals that are exclusively dependencies do this.

name

std::string nix::Goal::name

Name of this goal for debugging purposes.

nrFailed

size_t nix::Goal::nrFailed = 0

Number of goals we are/were waiting for that have failed.

nrIncompleteClosure

size_t nix::Goal::nrIncompleteClosure = 0

Number of substitution goals we are/were waiting for that failed because they had unsubstitutable references.

nrNoSubstituters

size_t nix::Goal::nrNoSubstituters = 0

Number of substitution goals we are/were waiting for that failed because there are no substituters.

worker

Worker& nix::Goal::worker

Backlink to the worker.
