Function AsDBitArray

pkg/sql/sem/tree/datum.go:546–552

AsDBitArray attempts to retrieve a *DBitArray from an Expr, returning a *DBitArray and a flag signifying whether the assertion was successful. The function should be used instead of direct type assertions.

(e Expr)

// a flag signifying whether the assertion was successful. The function should
// be used instead of direct type assertions.
func AsDBitArray(e Expr) (*DBitArray, bool) {
	switch t := e.(type) {
	case *DBitArray:
		return t, true
	}
	return nil, false
}
