Types

type ParserToLog

type ParserToLog struct {
	// Maps from external IDs to KID or offset.
	ExternalIDs map[string]logentry.KIDOrOffset
	// Maps from variable names to KID or offset.
	Variables map[string]logentry.KIDOrOffset
}

ParserToLog converts fields from parser.Insert into logentry values.

func (*ParserToLog) MustKGObject

func (converter *ParserToLog) MustKGObject(term parser.Term) logentry.KGObject

MustKGObject returns a non-zero value or panics. It panics if a necessary external ID or variable doesn't have a KIDorOffset value.

func (*ParserToLog) MustKIDOrOffset

func (converter *ParserToLog) MustKIDOrOffset(term parser.Term) logentry.KIDOrOffset

MustKIDOrOffset returns a non-zero value or panics. It panics if a necessary external ID or variable doesn't have a KIDorOffset value.

type ParserToRPC

type ParserToRPC struct {
	// Maps from external IDs to KIDs. Values of 0 are equivalent to missing
	// keys.
	ExternalIDs map[string]uint64
	// Maps from variable names to KIDs. Values of 0 are equivalent to missing
	// keys.
	Variables map[string]uint64
}

ParserToRPC converts fields from parser.Insert into RPC values.

func (*ParserToRPC) KGObject

func (converter *ParserToRPC) KGObject(term parser.Term) (rpc.KGObject, bool)

KGObject returns a non-empty KGObject and true if the term is convertible to a KGObject. Otherwise, it returns a zero KGObject and false.

func (*ParserToRPC) KID

func (converter *ParserToRPC) KID(term parser.Term) (uint64, bool)

KID returns a non-zero value and true if the term is convertible to a KID. Otherwise, it returns 0 and false.
