Merger provides state and methods to help manage the process of
merging together coverage counter data for a given function, for
tools that need to implicitly merge counter as they read multiple
coverage counter data files.
(*Merger) Granularity() coverage.CounterGranularity
MergeCounters takes the counter values in 'src' and merges them
into 'dst' according to the correct counter mode.
(*Merger) Mode() coverage.CounterMode
(*Merger) ResetModeAndGranularity()
Saturating add does a saturating addition of 'dst' and 'src',
returning added value or math.MaxUint32 if there is an overflow.
Overflows are recorded in case the client needs to track them.
SetModeAndGranularity records the counter mode and granularity for
the current merge. In the specific case of merging across coverage
data files from different binaries, where we're combining data from
more than one meta-data file, we need to check for and resolve
mode/granularity clashes.
(*Merger) SetModeMergePolicy(policy ModeMergePolicy)
func (*Merger).SetModeMergePolicy(policy ModeMergePolicy)
const ModeMergeRelaxed
const ModeMergeStrict
Package-Level Functions (only one)
Saturating add does a saturating addition of 'dst' and 'src',
returning added value or math.MaxUint32 plus an overflow flag.
