Tyler Yahn	493e13f834	Update metric types to not use pointer receivers (#462) ... The methods on the `Float64Gauge`, `Int64Gauge`, `Float64Counter`, `Int64Counter`, `Float64Measure`, and `Int64Measure` `struct`s do not need to mutate the internal state of the `struct` and can therefore be defined with value receivers instead. This aligns closer to the function signatures of each instruments constructor function. Additionally, this change means calls to these methods do not need an allocation to the heap.

Krzesimir Nowak	b3247f04fc	Update metrics API to match current spec (#228) ... * Update metrics API to match current spec * update options to match the spec * drop the global meter API * more docs * get rid of leftover mentions about descriptor	2019-10-22 23:29:24 -07:00
Krzesimir Nowak	388d3248fe	Some metrics followup (#177) ... * prevent passing observer descriptors to NewHandle * add some test for metrics * reword some docs	2019-10-15 09:28:36 -07:00
Joshua MacDonald	be8fb0b4e2	Golang metrics prototype (#100) ... * initial metrics work * rename cumulative to counter * rename bidirectional to nonmonotonic * rename unidirectional to monotonic * rename nonnegative to signed this changes the default semantics a bit - before the change measure could record negative values by default, now it can't. The specification draft currently specifies both NonNegative and Signed, but I think it's a mistake. * rename instrument to descriptor * license * rework measurement values * make measurement value a tagged union * simplify to one kind of metrics * add observers * change some interfaces to match the spec * keep integral measurement separate from floating ones * remove duplicated measurement type * add checking for options * reorder some fields and functions * rename a function to avoid confusion between the Handle type and the Measure type * drop disabled field from descriptor * add back typed API for metrics * make metric options type safe * merge alternatives into a single bool * make value kind name less stuttery * fix observation callback prototype * drop context parameter from NewHandle * drop useless parameter names * make descriptor an opaque struct * use a store helper * handle comment fixes * reword Alternate comment * drop the "any value" metrics * make measurement value simpler * document value stuff * add tests for values * docs * do not panic if there is no span ID in the event	2019-10-08 15:45:49 -07:00
