Package-Level Type Names (total 5)


	/* sort by:  |  */
	
		Batch represents an event batch.

		
			
				Event emits an event into a batch. name must correspond to one
				of the names in Specs() result for the version that was passed to
				this trace. Callers must omit the timestamp delta.

			
				RawEvent emits an event into a batch. name must correspond to one
				of the names in Specs() result for the version that was passed to
				this trace.

		
			func (*Generation).Batch(thread trace.ThreadID, time Time) *Batch


	
		Generation represents a single generation in the trace.

		
			
				Batch starts a new event batch in the trace data.
				
				This is convenience function for generating correct batches.

			
				Stack registers a stack with the trace.
				
				This is a convenience function for easily adding correct
				stacks to traces.

			
				String registers a string with the trace.
				
				This is a convenience function for easily adding correct
				strings to traces.

		
			func (*Trace).Generation(gen uint64) *Generation


	
		Seq represents a sequence counter.


	
		Time represents a low-level trace timestamp (which does not necessarily
		correspond to nanoseconds, like trace.Time does).

		
			func (*Generation).Batch(thread trace.ThreadID, time Time) *Batch


	
		Trace represents an execution trace for testing.
		
		It does a little bit of work to ensure that the produced trace is valid,
		just for convenience. It mainly tracks batches and batch sizes (so they're
		trivially correct), tracks strings and stacks, and makes sure emitted string
		and stack batches are valid. That last part can be controlled by a few options.
		
		Otherwise, it performs no validation on the trace at all.

		
			
				DisableTimestamps makes the timestamps for all events generated after
				this call zero. Raw events are exempted from this because the caller
				has to pass their own timestamp into those events anyway.

			
				ExpectFailure writes down that the trace should be broken. The caller
				must provide a pattern matching the expected error produced by the parser.

			
				ExpectSuccess writes down that the trace should successfully parse.

			
				Generate creates a test file for the trace.

			
				Generation creates a new trace generation.
				
				This provides more structure than Event to allow for more easily
				creating complex traces that are mostly or completely correct.

			
				RawEvent emits an event into the trace. name must correspond to one
				of the names in Specs() result for the version that was passed to
				this trace.

		
			func NewTrace() *Trace
