Method ReadVarint64

go/fory/buffer.go:1052–1059

ReadVarint64 reads the varint encoded with zig-zag (compatible with Java's readVarint64).

(err *Error)

// ReadVarint64 reads the varint encoded with zig-zag (compatible with Java's readVarint64).
func (b *ByteBuffer) ReadVarint64(err *Error) int64 {
	u := b.ReadVarUint64(err)
	v := int64(u >> 1)
	if u&1 != 0 {
		v = ^v
	}
	return v
}

// WriteTaggedInt64 writes int64 using tagged encoding.
// If value is in [-1073741824, 1073741823], encode as 4 bytes: ((value as i32) << 1).
