Functions

func ConnReadN added in v0.0.62

func ConnReadN(ctx context.Context, reader io.Reader, N int64) ([]byte, error)

ConnReadN reads at most N bytes from reader and it optimized for connection based readers like net.Conn it should not be used for file/buffer based reading, ConnReadN should be preferred instead of 'conn.Read() without loop' . It ignores EOF, UnexpectedEOF and timeout errors Note: you are responsible for adding a timeout to context

func ConnReadNWithTimeout added in v0.0.62

func ConnReadNWithTimeout(reader io.Reader, N int64, after time.Duration) ([]byte, error)

ConnReadNWithTimeout is same as ConnReadN but it takes timeout instead of context and it returns error if read does not finish in given time

func IsAcceptedError added in v0.0.62

func IsAcceptedError(err error) bool

IsAcceptedError checks if the error is accepted error for example: connection refused, io.EOF, io.ErrUnexpectedEOF while reading from connection
