type CoverageMetaDataDecoder struct {// contains filtered or unexported fields}

funcNewCoverageMetaDataDecoder¶

func NewCoverageMetaDataDecoder(b []byte, readonlybool) (*CoverageMetaDataDecoder,error)

func (*CoverageMetaDataDecoder)ModulePath¶

func (d *CoverageMetaDataDecoder) ModulePath()string

func (*CoverageMetaDataDecoder)NumFuncs¶

func (d *CoverageMetaDataDecoder) NumFuncs()uint32

func (*CoverageMetaDataDecoder)PackageName¶

func (d *CoverageMetaDataDecoder) PackageName()string

func (*CoverageMetaDataDecoder)PackagePath¶

func (d *CoverageMetaDataDecoder) PackagePath()string

func (*CoverageMetaDataDecoder)ReadFunc¶

func (d *CoverageMetaDataDecoder) ReadFunc(fidxuint32, f *coverage.FuncDesc)error

ReadFunc reads the coverage meta-data for the function with index'findex', filling it into the FuncDesc pointed to by 'f'.

type CoverageMetaFileReader struct {// contains filtered or unexported fields}

funcNewCoverageMetaFileReader¶

func NewCoverageMetaFileReader(f *os.File, fileView []byte) (*CoverageMetaFileReader,error)

NewCoverageMetaFileReader returns a new helper object for readingthe coverage meta-data output file 'f'. The param 'fileView' is aread-only slice containing the contents of 'f' obtained by mmap'ingthe file read-only; 'fileView' may be nil, in which case the helperwill read the contents of the file using regular file Readoperations.

func (*CoverageMetaFileReader)CounterGranularity¶

func (r *CoverageMetaFileReader) CounterGranularity()coverage.CounterGranularity

CounterGranularity returns the counter granularity (single counter perfunction, or counter per block) selected when building for coveragefor the program that produce this meta-data file.

func (*CoverageMetaFileReader)CounterMode¶

func (r *CoverageMetaFileReader) CounterMode()coverage.CounterMode

CounterMode returns the counter mode (set, count, atomic) usedwhen building for coverage for the program that produce thismeta-data file.

func (*CoverageMetaFileReader)FileHash¶

func (r *CoverageMetaFileReader) FileHash() [16]byte

FileHash returns the hash computed for all of the package meta-datablobs. Coverage counter data files refer to this hash, and thehash will be encoded into the meta-data file name.

func (*CoverageMetaFileReader)GetPackageDecoder¶

func (r *CoverageMetaFileReader) GetPackageDecoder(pkIdxuint32, payloadbuf []byte) (*CoverageMetaDataDecoder, []byte,error)

GetPackageDecoder requests a decoder object for the package withinthe meta-data file whose index is 'pkIdx'. If theCoverageMetaFileReader was set up with a read-only file view, apointer into that file view will be returned, otherwise the buffer'payloadbuf' will be written to (or if it is not of sufficientsize, a new buffer will be allocated). Return value is the decoder,a byte slice with the encoded meta-data, and an error.

func (*CoverageMetaFileReader)GetPackagePayload¶

func (r *CoverageMetaFileReader) GetPackagePayload(pkIdxuint32, payloadbuf []byte) ([]byte,error)

GetPackagePayload returns the raw (encoded) meta-data payload for thepackage with index 'pkIdx'. As with GetPackageDecoder, if theCoverageMetaFileReader was set up with a read-only file view, apointer into that file view will be returned, otherwise the buffer'payloadbuf' will be written to (or if it is not of sufficientsize, a new buffer will be allocated). Return value is the decoder,a byte slice with the encoded meta-data, and an error.

func (*CoverageMetaFileReader)NumPackages¶

func (r *CoverageMetaFileReader) NumPackages()uint64

NumPackages returns the number of packages for which this filecontains meta-data.
