Overview

Package pquads implements Cayley-specific protobuf-based quads format. 

Package pquads is a generated protocol buffer package.

It is generated from these files:
	quads.proto

It has these top-level messages:
	Quad
	WireQuad
	StrictQuad
	Value
	Header

Functions

func MarshalValue 

func MarshalValue(v quad.Value) ([]byte, error)

Types 

type Header struct {
	// Full is set if encoder always writes every quad directions instead of
	// skipping duplicated values on each direction (except label) for subsequent quads.
	Full bool `protobuf:"varint,1,opt,name=full,proto3" json:"full,omitempty"`
	// NotStrict is set if encoder emits WireQuad instead of StrictQuad messages.
	NotStrict bool `protobuf:"varint,2,opt,name=not_strict,json=notStrict,proto3" json:"not_strict,omitempty"`
