While working on #4680 I found out that if you have a cfg like
cfg(flag)
this will causecargo run -p document-metrics
to error withError: expected '='
.This is an attempt to avoid that and instead treat it like
cfg(feature=flag)
.NOTE: This might not be the best approach, we might want to ignore the enum variant instead if it is guarded by a
cfg
