// The supported units are a subset of [The Unified Code for Units of

|
// Measure](https://unitsofmeasure.org/ucum.html) standard:

|
// **Basic units (UNIT)**
|
|
//
|
|
// * `bit` bit
|
|
// * `By` byte
|
|
// * `s` second
|
|
// * `min` minute
|
|
// * `h` hour
|
|
// * `d` day
|
|
// * `1` dimensionless
|
|
//
|
|
// **Prefixes (PREFIX)**
|
|
//
|
|
// * `k` kilo (10^3)
|
|
// * `M` mega (10^6)
|
|
// * `G` giga (10^9)
|
|
// * `T` tera (10^12)
|
|
// * `P` peta (10^15)
|
|
// * `E` exa (10^18)

|
|
// **Grammar**
|
|
//
|
|
// The grammar also includes these connectors:
|
|
//
|
|
// * `/` division or ratio (as an infix operator). For examples,
|
|
// `kBy/{email}` or `MiBy/10ms` (although you should almost never
|
|
// have `/s` in a metric `unit`; rates should always be computed at
|
|
// query time from the underlying cumulative or delta value).
|
|
// * `.` multiplication or composition (as an infix operator). For
|
|
// examples, `GBy.d` or `k{watt}.h`.
|
|
//
|
|
// The grammar for a unit is as follows:
|
|
//
|
|
// Expression = Component { "." Component } { "/" Component } ;
|
|
//
|
|
// Component = ( [ PREFIX ] UNIT | "%" ) [ Annotation ]
|
|
// | Annotation
|
|
// | "1"
|
|
// ;
|
|
//
|
|
// Annotation = "{" NAME "}" ;
|
|
//
|
|
// Notes:
|
|
//
|
|
// * `Annotation` is just a comment if it follows a `UNIT`. If the annotation
|
|
// is used alone, then the unit is equivalent to `1`. For examples,
|
|
// `{request}/s == 1/s`, `By{transmitted}/s == By/s`.
|
|
// * `NAME` is a sequence of non-blank printable ASCII characters not
|
|
// containing `{` or `}`.
|
|
// * `1` represents a unitary [dimensionless
|
|
// unit](https://en.wikipedia.org/wiki/Dimensionless_quantity) of 1, such
|
|
// as in `1/s`. It is typically used when none of the basic units are
|
|
// appropriate. For example, "new users per day" can be represented as
|
|
// `1/d` or `{new-users}/d` (and a metric value `5` would mean "5 new
|
|
// users). Alternatively, "thousands of page views per day" would be
|
|
// represented as `1000/d` or `k1/d` or `k{page_views}/d` (and a metric
|
|
// value of `5.3` would mean "5300 page views per day").
|
|
// * `%` represents dimensionless value of 1/100, and annotates values giving
|
|
// a percentage (so the metric values are typically in the range of 0..100,
|
|
// and a metric value `3` means "3 percent").
|
|
// * `10^2.%` indicates a metric contains a ratio, typically in the range
|
|
// 0..1, that will be multiplied by 100 and displayed as a percentage
|
|
// (so a metric value `0.03` means "3 percent").
