List of labels;
nonconfigurable; default is the package's
default_package_metadata
A list of labels that are associated metadata about this target. Typically, the labels are simple rules that return a provider of constant values. Rules and aspects may use these labels to perform some additional analysis on the build graph.
The canonical use case is that of
rules_license.
For that use case, package_metadata
and
default_package_metadata
is used to attach information
about a package's licence or version to targets. An aspect applied
to a top-level binary can be used to gather those and produce
compliance reports.
