}CounterGranularity returns the counter granularity (single counter per function, or counter per block) selected when building for coverage for the program that produce this meta-data file.
func (r *CoverageMetaFileReader) CounterGranularity() coverage.CounterGranularityCounterMode returns the counter mode (set, count, atomic) used when building for coverage for the program that produce this meta-data file.
func (r *CoverageMetaFileReader) CounterMode() coverage.CounterModeFileHash returns the hash computed for all of the package meta-data blobs. Coverage counter data files refer to this hash, and the hash will be encoded into the meta-data file name.
func (r *CoverageMetaFileReader) FileHash() [16]byteGetPackageDecoder requests a decoder object for the package within the meta-data file whose index is 'pkIdx'. If the CoverageMetaFileReader was set up with a read-only file view, a pointer into that file view will be returned, otherwise the buffer 'payloadbuf' will be written to (or if it is not of sufficient size, a new buffer will be allocated). Return value is the decoder, a byte slice with the encoded meta-data, and an error.
func (r *CoverageMetaFileReader) GetPackageDecoder(pkIdx uint32, payloadbuf []byte) (*CoverageMetaDataDecoder, []byte, error)GetPackagePayload returns the raw (encoded) meta-data payload for the package with index 'pkIdx'. As with GetPackageDecoder, if the CoverageMetaFileReader was set up with a read-only file view, a pointer into that file view will be returned, otherwise the buffer 'payloadbuf' will be written to (or if it is not of sufficient size, a new buffer will be allocated). Return value is the decoder, a byte slice with the encoded meta-data, and an error.
func (r *CoverageMetaFileReader) GetPackagePayload(pkIdx uint32, payloadbuf []byte) ([]byte, error)func (d *CoverageMetaDataDecoder) ModulePath() stringfunc NewCoverageMetaDataDecoder(b []byte, readonly bool) (*CoverageMetaDataDecoder, error)NewCoverageMetaFileReader returns a new helper object for reading the coverage meta-data output file 'f'. The param 'fileView' is a read-only slice containing the contents of 'f' obtained by mmap'ing the file read-only; 'fileView' may be nil, in which case the helper will read the contents of the file using regular file Read operations.
func NewCoverageMetaFileReader(f *os.File, fileView []byte) (*CoverageMetaFileReader, error)func (d *CoverageMetaDataDecoder) NumFuncs() uint32NumPackages returns the number of packages for which this file contains meta-data.
func (r *CoverageMetaFileReader) NumPackages() uint64func (d *CoverageMetaDataDecoder) PackageName() stringfunc (d *CoverageMetaDataDecoder) PackagePath() stringReadFunc reads the coverage meta-data for the function with index 'findex', filling it into the FuncDesc pointed to by 'f'.
