Detailed Description
Class that represents the trace range associated with a given TSC. It provides efficient iteration to the previous or next TSC range in the decoded trace.
TSC timestamps are emitted by the decoder infrequently, which means that each TSC covers a range of instruction indices, which can be used to speed up TSC lookups.
