Exported Type Names

type Demangler (func) Demangler maps symbol names to a human-readable form. This may include C++ demangling and additional simplification. Names that are not demangled may be missing from the resulting map. func (*Profile).Demangle(d Demangler) error

Exported Values
var LegacyHeapAllocated bool LegacyHeapAllocated instructs the heapz parsers to use the allocated memory stats instead of the default in-use memory. Note that tcmalloc doesn't provide all allocated memory, only in-use stats.
func Merge(srcs []*Profile) (*Profile, error) Merge merges all the profiles in profs into a single Profile. Returns a new profile independent of the input profiles. The merged profile is compacted to eliminate unused samples, locations, functions and mappings. Profiles must have identical profile sample and period types or the merge will fail. profile.Period of the resulting profile will be the maximum of all profiles, and profile.TimeNanos will be the earliest nonzero one.
func Parse(r io.Reader) (*Profile, error) Parse parses a profile and checks for its validity. The input may be a gzip-compressed encoded protobuf or one of many legacy profile formats which may be unsupported in the future.
func ParseTracebacks(b []byte) (*Profile, error) ParseTracebacks parses a set of tracebacks and returns a newly populated profile. It will accept any text file and generate a Profile out of it with any hex addresses it can identify, including a process map if it can recognize one. Each sample will include a tag "source" with the addresses recognized in string format.
