namespace extensions {
namespace functions {

// Short version:
//  *Never* reorder or delete entries in the |HistogramValue| enumeration.
//  When creating a new extension function, add a new entry at the end of the
//  enum, just prior to ENUM_BOUNDARY.
//
// Long version:
//  This enumeration is used to associate a unique integer value to each
//  extension function so that their usage can be recorded in histogram charts.
//  Given we want the values recorded in the these charts to remain stable over
//  time for comparison purposes, once an entry has been added to the
//  enumeration, it should never be removed or moved to another spot in the
//  enum.
//
//  Here are instructions how to manage entries depending on what you are trying
//  to achieve.
//
//  1) Creating a new extension function:
//
//      Add a new entry at the end of the |HistogramValue| enum. The name of the
//      entry should follow this algorithm:
//      a) Take the string value passed as first argument to
//         DECLARE_EXTENSION_FUNCTION.
//      b) Replace '.' with '_'.
//      c) Make all letters uppercase.
//
//      Example: "tabs.create" -> TABS_CREATE
//
//  2) Deleting an existing function:
//
//      Given an existing entry should *never* be removed from this enumeration,
//      it is recommended to add a "DELETED_" prefix to the existing entry.
//
//  3) Renaming an existing function:
//
//      There are 2 options, depending if you want to keep accruing data in the
//      *existing* histogram stream or in a *new* one.
//
//      a) If you want keep recording usages of the extension function in the
//         *existing* histogram stream, simply rename the enum entry to match
//         the new extension function name, following the same naming rule as
//         mentioned in 1). The enum entry will keep the same underlying integer
//         value, so the same histogram stream will be used for recording
//         usages.
//
//      b) If you want start recording usages of the extension function to in a
//         *new* histogram stream, follow the instructions in step 1) and 2)
//         above. This will effectively deprecate the old histogram stream and
//         creates a new one for the new function name.
//
