Types

type DriverItem

type DriverItem struct {
	*datasource.SqlDriverMessageMap
}

func (*DriverItem) Less

func (m *DriverItem) Less(than btree.Item) bool

type Key

type Key struct {
	Id uint64
}

func NewKey

type StaticDataSource

type StaticDataSource struct {
	*schema.Schema
	// contains filtered or unexported fields
}

Static DataSource, implements qlbridge DataSource to allow in memory native go data

to have a Schema and implement and be operated on by Sql Operations

Features - only a single column may (and must) be identified as the "Indexed" column - NOT threadsafe - each StaticDataSource = a single Table

func NewStaticData

func NewStaticDataSource

func NewStaticDataSource(name string, indexedCol int, data [][]driver.Value, cols []string) *StaticDataSource

func NewStaticDataValue

func NewStaticDataValue(name string, data interface{}) *StaticDataSource

StaticDataValue is used to create a static name=value pair that matches
