Namespaces
namespace	tide
namespace	tide::vint
	Functions for managing variable-length integers.
Typedefs
typedef std::pair< uint64_t, std::streamsize >	tide::vint::OffsetInt
	The result type of s_to_u().
typedef std::pair< uint64_t, std::vector< char > ::const_iterator >	tide::vint::DecodeResult
	The result of a decode operation is a pair of the integer decoded and an iterator pointing to the first element after the used data.
typedef std::pair< uint64_t, std::streamsize >	tide::vint::ReadResult
	The result of a read operation is a pair of the integer read and the number of bytes read.
Functions
std::streamsize	tide::vint::size (uint64_t integer)
	Get the size of an integer after encoding.
OffsetInt	tide::vint::s_to_u (int64_t integer)
	Offsets a signed integer into unsigned territory.
int64_t	tide::vint::u_to_s (OffsetInt integer)
	Offsets an unsigned integer into signed territory.
std::vector< char >	tide::vint::encode (uint64_t integer, std::streamsize req_size=0)
	Encode an unsigned integer into a buffer.
DecodeResult	tide::vint::decode (std::vector< char > const &buffer)
	Decode an unsigned variable-length integer from a buffer.
std::streamsize	tide::vint::write (uint64_t integer, std::ostream &output, std::streamsize req_size=0)
	Encode an unsigned integer and write it to an output stream.
ReadResult	tide::vint::read (std::istream &input)
	Decode an unsigned integer from an input stream.
