JobCategory

enum struct nix::JobCategory

strong

Used as a hint to the worker on how to schedule a particular goal. For example, builds are typically CPU- and memory-bound, while substitutions are I/O bound. Using this information, the worker might decide to schedule more or fewer goals of each category in parallel.

Enumerator
Build	A build of a derivation; it will use CPU and disk resources.
Substitution	A substitution an arbitrary store object; it will use network resources.
