Functions

func GetBuffer

func GetBuffer() *bytes.Buffer

GetBuffer returns a reset *bytes.Buffer from the pool.

func PutBuffer

func PutBuffer(b *bytes.Buffer)

PutBuffer returns a *bytes.Buffer to the pool. Buffers that have grown unreasonably large are discarded to avoid pinning large slices.

func WriteAtomic

func WriteAtomic(path string, data []byte) error

WriteAtomic writes data to path via a sibling .tmp file followed by rename, so readers tailing the directory never see a partially-written JSON file.
