Package service is the definition of the RPC GPU debugger service exposed by the server.

It is not the actual implementation of the service functionality.

Types

type FindHandler

type FindHandler func(*FindResponse) error

FindHandler is the handler of found items using Service.Find.

type ReportBuilder

type ReportBuilder struct {
	// contains filtered or unexported fields
}

ReportBuilder helps construct reports.

func NewReportBuilder

func NewReportBuilder() *ReportBuilder

NewReportBuilder creates and initializes new report builder.

func (*ReportBuilder) Add

func (b *ReportBuilder) Add(ctx context.Context, element *ReportItemRaw)

Add processes tags, adds references to item and adds item to report.

func (*ReportBuilder) Build

func (b *ReportBuilder) Build() *Report

Build performs final processing and returns report.

type ReportItemRaw

type ReportItemRaw struct {
	Item    *ReportItem
	Message *stringtable.Msg
	Tags    []*stringtable.Msg
}

ReportItemRaw represents ReportItem, raw message and array of raw tags.

func WrapReportItem

func WrapReportItem(item *ReportItem, m *stringtable.Msg) *ReportItemRaw

WrapReportItem wraps ReportItem into raw representation of ReportItemTagged which contains raw messages instead of references.

type Service
