	// contains filtered or unexported fields
}

type ParserConfig

type ParserConfig struct {
	Putter              storage.Putter
	SpyName             string
	Labels              map[string]string
	SkipExemplars       bool
	SampleTypes         map[string]*tree.SampleTypeConfig
	StackFrameFormatter StackFrameFormatter
}

type ParserInterface

type ParserInterface interface {
	ParsePprof(ctx context.Context, startTime, endTime time.Time, bs []byte, cumulativeOnly bool) error
}

type RawProfile

type RawProfile struct {

	// Initializes lazily on Bytes, if not present.
	RawData             []byte // Represents raw request body as per ingestion API.
	FormDataContentType string // Set optionally, if RawData is multipart form.
	// Initializes lazily on Parse, if not present.
	Profile             []byte // Represents raw pprof data.
	PreviousProfile     []byte // Used for cumulative type only.
	SkipExemplars       bool
	StreamingParser     bool
	PoolStreamingParser bool
	ArenasEnabled       bool
	SampleTypeConfig    map[string]*tree.SampleTypeConfig
	// contains filtered or unexported fields
}

func (*RawProfile) Bytes

func (p *RawProfile) Bytes() ([]byte, error)

func (*RawProfile) ContentType

func (p *RawProfile) ContentType() string

func (*RawProfile) Parse

func (p *RawProfile) Parse(ctx context.Context, putter storage.Putter, _ storage.MetricsExporter, md ingestion.Metadata) error

func (*RawProfile) ParseWithWriteBatch

func (p *RawProfile) ParseWithWriteBatch(c context.Context, wb stackbuilder.WriteBatchFactory, md ingestion.Metadata) error

func (*RawProfile) Push

func (p *RawProfile) Push(profile []byte, cumulative bool) *RawProfile

Push loads data from profile to RawProfile making it eligible for Bytes and Parse calls.

Returned RawProfile should be used at the next Push: the method established relationship between these two RawProfiles in order to propagate internal pprof parser state lazily on a successful Parse call. This is necessary for cumulative profiles that require two consecutive samples to calculate the diff. If parser is not present due to a failure, or sequence violation, the profiles will be re-parsed.
