HardCodedPkgID returns the hard-coded ID for the specified package path, or -1 if we don't use a hard-coded ID.

CounterFilePref is the file prefix used when emitting coverage data output files.

CounterFileVersion stores the most recent counter data file version.

"atomic" mode.

"count" mode.

registration-only pseudo-mode.

"set" mode.

testmain pseudo-mode.

"Raw" representation: all values (pkg ID, func ID, num counters, and counters themselves) are stored as uint32's.

"ULeb" representation: all values (pkg ID, func ID, num counters, and counters themselves) are stored with ULEB128 encoding.

MetaFilePref is a prefix used when emitting meta-data files; these files are of the form "covmeta.<hash>", where hash is a hash computed from the hashes of all the package meta-data symbols in the program.

Name of file within the "go test -cover" temp coverdir directory containing a list of meta-data files for packages being tested in a "go test -coverpkg=..

MetaFileVersion contains the current (most recent) meta-data file version.

NotHardCoded is a package pseudo-ID indicating that a given package is not part of the runtime and doesn't require a hard-coded ID.

CovCounterMagic holds the magic string for a coverage counter-data file.

CovMetaMagic holds the magic string for a meta-data file.

CounterFileFooter appears at the tail end of a counter data file, and stores the number of segments it contains.

CounterFileHeader stores files header information for a counter-data file.

CounterSegmentHeader encapsulates information about a specific segment in a counter data file, which at the moment contains counters data from a single execution of a coverage-instrumented program.

CoverableUnit describes the source characteristics of a single program unit for which we want to gather coverage info.

FuncDesc encapsulates the meta-data definitions for a single Go function.

MetaFilePaths contains information generated by the Go command and the read in by coverage test support functions within an executing "go test -cover" binary.

MetaFileHeader stores file header information for a meta-data file.

MetaSymbolHeader stores header information for a single meta-data blob, e.g.

CounterFlavor describes how function and counters are stored/represented in the counter section of the file.

CounterGranularity tracks the granularity of the coverage counters being used in a given coverage-instrumented program.

CounterMode tracks the "flavor" of the coverage counters being used in a given coverage-instrumented program.
