FeatureMap.for_backtrace can be given a backtrace and will either return nil, or a CodeFeatures::Feature.

This will go through the backtrace, and return the feature of the first files with a feature assignment associated with frames within the backtrace.

See feature_map_spec.rb for an example.

Command

FeatureMap.for_backtrace(exception.backtrace)

Note: There is no command line utility for for_backtrace; this command is available only within the Ruby runtime.
