Types

type AstHandle

type AstHandle struct {
	// contains filtered or unexported fields
}

AstHandle wraps the underlying TiDB ast, to avoid leaking the TiDB too much into the rest of the code

type Parser

type Parser struct {
	// contains filtered or unexported fields
}

func NewParser

type Planner struct {
	// contains filtered or unexported fields
}
