Functions

func CheckArgCount 

func CheckArgCount(narg int, argmin int, argmax int) error

func HasBoolResult 

func HasBoolResult(name string) bool

HasBoolResult returns true if the function name returns a Boolean value. XXX This is a hack so the semantic compiler can determine if a single call expr is a Filter or Put proc. At some point function declarations should have signatures so the return type can be introspected.

func New 

func New(zctx *zed.Context, name string, narg int) (expr.Function, field.Path, error)

func TypeLength added in v1.18.0 

func TypeLength(typ zed.Type) int

func NewNestDotted 

func NewNestDotted(zctx *zed.Context) *NestDotted
