Functions

AddFunc method #

AddFunc registers a new function with the meta data builder.

func (b *CoverageMetaDataBuilder) AddFunc(f coverage.FuncDesc) uint

Emit method #

Emit writes the meta-data accumulated so far in this builder to 'w'. Returns a hash of the meta-data payload and an error.

func (b *CoverageMetaDataBuilder) Emit(w io.WriteSeeker) ([16]byte, error)

HashFuncDesc function #

HashFuncDesc computes an md5 sum of a coverage.FuncDesc and returns a digest for it.

func HashFuncDesc(f *coverage.FuncDesc) [16]byte

NewCoverageMetaDataBuilder function # 

func NewCoverageMetaDataBuilder(pkgpath string, pkgname string, modulepath string) (*CoverageMetaDataBuilder, error)

NewCoverageMetaFileWriter function # 

func NewCoverageMetaFileWriter(mfname string, w io.Writer) *CoverageMetaFileWriter

Write method # 

func (m *CoverageMetaFileWriter) Write(finalHash [16]byte, blobs [][]byte, mode coverage.CounterMode, granularity coverage.CounterGranularity) error

emitFunc method # 

func (b *CoverageMetaDataBuilder) emitFunc(w io.WriteSeeker, off int64, f funcDesc) (int64, error)

emitFuncOffsets method # 

func (b *CoverageMetaDataBuilder) emitFuncOffsets(w io.WriteSeeker, off int64) int64

h32 function # 

func h32(x uint32, h hash.Hash, tmp []byte)

hashFuncDesc function #

hashFuncDesc incorporates a given function 'f' into the hash 'h'.

func hashFuncDesc(h hash.Hash, f *coverage.FuncDesc, tmp []byte)

reportWriteError method # 

func (b *CoverageMetaDataBuilder) reportWriteError(err error)

wrUint32 method # 

func (b *CoverageMetaDataBuilder) wrUint32(w io.WriteSeeker, v uint32)
