-// results in a single line defer at the top of a function time a function.

-//   timing := FromContext(r.Context())
-//   defer timing.NewMetric("sql").Start().Stop()
-//
-// For timing around specific blocks of code:
-//
-//   m := timing.NewMetric("sql").Start()
-//   // ... run your code being timed here
-//   m.Stop()
-//
-// A metric is expected to represent a single timing event. Therefore,
-// no functions on the struct are safe for concurrency by default. If a single
-// Metric is shared by multiple concurrenty goroutines, you must lock access
-// manually.
-type Metric struct {
-	// Name is the name of the metric. This must be a valid RFC7230 "token"
-	// format. In a gist, this is an alphanumeric string that may contain
-	// most common symbols but may not contain any whitespace. The exact
-	// syntax can be found in RFC7230.
-	//
-	// It is common for Name to be a unique identifier (such as "sql-1") and
-	// for a more human-friendly name to be used in the "desc" field.

-	// be any "token | quoted-string" (same as Desc field).
