package core Import Path golang.org/x/tools/internal/event/core (on go.dev) Dependency Relation imports 7 packages, and imported by one package Involved Source Files #d event.go Package core provides support for event based telemetry. export.go fast.go Package-Level Type Names (total 3, in which 2 are exported) /* sort exporteds by: alphabet | popularity */ type Event (struct) Event holds the information about an event of note that occurred. Fields (total 3, none are exported) /* 3 unexporteds ... *//* 3 unexporteds: */ at time.Time dynamic []label.Label // dynamically sized storage for remaining labels static [3]label.Label // inline storage for the first few labels Methods (total 5, all are exported) ( Event) At() time.Time ( Event) Find(key label.Key) label.Label ( Event) Format(f fmt.State, r rune) ( Event) Label(index int) label.Label ( Event) Valid(index int) bool Implements (at least 3, all are exported) Event : golang.org/x/tools/internal/event/label.List Event : golang.org/x/tools/internal/event/label.Map Event : fmt.Formatter As Outputs Of (at least 2, both are exported) func CloneEvent(ev Event, at time.Time) Event func MakeEvent(static [3]label.Label, labels []label.Label) Event As Inputs Of (at least 11, in which 10 are exported) func CloneEvent(ev Event, at time.Time) Event func Export(ctx context.Context, ev Event) context.Context func ExportPair(ctx context.Context, begin, end Event) (context.Context, func()) func golang.org/x/tools/internal/event.IsDetach(ev Event) bool func golang.org/x/tools/internal/event.IsEnd(ev Event) bool func golang.org/x/tools/internal/event.IsError(ev Event) bool func golang.org/x/tools/internal/event.IsLabel(ev Event) bool func golang.org/x/tools/internal/event.IsLog(ev Event) bool func golang.org/x/tools/internal/event.IsMetric(ev Event) bool func golang.org/x/tools/internal/event.IsStart(ev Event) bool /* at least one unexported ... *//* at least one unexported: */ func deliver(ctx context.Context, exporter Exporter, ev Event) context.Context type Exporter (func) Exporter is a function that handles events. It may return a modified context and event. As Inputs Of (at least 2, in which 1 are exported) func SetExporter(e Exporter) /* at least one unexported ... *//* at least one unexported: */ func deliver(ctx context.Context, exporter Exporter, ev Event) context.Context /* one unexported ... *//* one unexported: */ type eventLabelMap (struct) eventLabelMap implements label.Map for a the labels of an Event. Fields (only one, which is unexported) /* one unexported ... *//* one unexported: */ event Event Package-Level Functions (total 12, in which 11 are exported) func CloneEvent(ev Event, at time.Time) Event CloneEvent event returns a copy of the event with the time adjusted to at. func Export(ctx context.Context, ev Event) context.Context Export is called to deliver an event to the global exporter if set. func ExportPair(ctx context.Context, begin, end Event) (context.Context, func()) ExportPair is called to deliver a start event to the supplied exporter. It also returns a function that will deliver the end event to the same exporter. It will fill in the time. func Log1(ctx context.Context, message string, t1 label.Label) Log1 takes a message and one label delivers a log event to the exporter. It is a customized version of Print that is faster and does no allocation. func Log2(ctx context.Context, message string, t1 label.Label, t2 label.Label) Log2 takes a message and two labels and delivers a log event to the exporter. It is a customized version of Print that is faster and does no allocation. func MakeEvent(static [3]label.Label, labels []label.Label) Event func Metric1(ctx context.Context, t1 label.Label) context.Context Metric1 sends a label event to the exporter with the supplied labels. func Metric2(ctx context.Context, t1, t2 label.Label) context.Context Metric2 sends a label event to the exporter with the supplied labels. func SetExporter(e Exporter) SetExporter sets the global exporter function that handles all events. The exporter is called synchronously from the event call site, so it should return quickly so as not to hold up user code. func Start1(ctx context.Context, name string, t1 label.Label) (context.Context, func()) Start1 sends a span start event with the supplied label list to the exporter. It also returns a function that will end the span, which should normally be deferred. func Start2(ctx context.Context, name string, t1, t2 label.Label) (context.Context, func()) Start2 sends a span start event with the supplied label list to the exporter. It also returns a function that will end the span, which should normally be deferred. /* one unexported ... *//* one unexported: */ func deliver(ctx context.Context, exporter Exporter, ev Event) context.Context deliver is called to deliver an event to the supplied exporter. it will fill in the time. Package-Level Variables (only one, which is unexported) /* one unexported ... *//* one unexported: */ var exporter unsafe.Pointer
