var frameFields = []string{...}Event is a simple representation of a trace event. Note that this typically includes much more than just timestamped events, and it also represents parts of the trace format's framing. (But not interpreted.)
type Event struct {
Version version.Version
Ev event.Type
Args []uint64
Data []byte
}Reader parses trace bytes with only very basic validation into an event stream.
type Reader struct {
r *bufio.Reader
v version.Version
specs []event.Spec
}TextReader parses a text format trace with only very basic validation into an event stream.
type TextReader struct {
v version.Version
specs []event.Spec
names map[string]event.Type
s *bufio.Scanner
}TextWriter emits the text format of a trace.
type TextWriter struct {
w io.Writer
v version.Version
}Writer emits the wire format of a trace. It may not produce a byte-for-byte compatible trace from what is produced by the runtime, because it may be missing extra padding in the LEB128 encoding that the runtime adds but isn't necessary when you know the data up-front.
type Writer struct {
w io.Writer
buf []byte
v version.Version
specs []event.Spec
}EncodedSize returns the canonical encoded size of an event.
func (e *Event) EncodedSize() intNewReader creates a new reader for the trace wire format.
func NewReader(r io.Reader) (*Reader, error)NewTextReader creates a new reader for the trace text format.
func NewTextReader(r io.Reader) (*TextReader, error)NewTextWriter creates a new write for the trace text format.
func NewTextWriter(w io.Writer, v version.Version) (*TextWriter, error)NewWriter creates a new byte format writer.
func NewWriter(w io.Writer, v version.Version) (*Writer, error)ReadEvent reads and returns the next trace event in the byte stream.
func (r *Reader) ReadEvent() (Event, error)ReadEvent reads and returns the next trace event in the text stream.
func (r *TextReader) ReadEvent() (Event, error)String returns the canonical string representation of the event. This format is the same format that is parsed by the TextReader and emitted by the TextWriter.
func (e *Event) String() stringVersion returns the version of the trace that we're reading.
func (r *Reader) Version() version.VersionVersion returns the version of the trace that we're reading.
func (r *TextReader) Version() version.VersionWriteEvent writes a single event to the stream.
func (w *TextWriter) WriteEvent(e Event) errorWriteEvent writes a single event to the trace wire format stream.
