This file describes the enumerations referenced by entries in histograms.xml for
this directory. Some enums may instead be listed in the central enums.xml file
at src/tools/metrics/histograms/enums.xml when multiple files use them.
For best practices on writing enumerations descriptions, see
https://chromium.googlesource.com/chromium/src.git/+/HEAD/tools/metrics/histograms/README.md#Enum-Histograms
Please follow the instructions in the OWNERS file in this directory to find a
reviewer. If no OWNERS file exists, please consider signing up at
go/reviewing-metrics (Googlers only), as all subdirectories are expected to
have an OWNERS file. As a last resort you can send the CL to
[email protected].
