Functions

func DefaultEnv

func DefaultEnv(useUTC bool) (*cel.Env, error)

DefaultEnv produces a cel.Env with the necessary cel.EnvOption and cel.ProgramOption values preconfigured for usage throughout the module. If useUTC is true, timestamp operations use the UTC timezone instead of the local timezone.

func ProtoFieldToCELType

func ProtoFieldToCELType(fieldDesc protoreflect.FieldDescriptor, generic, forItems bool) *cel.Type

ProtoFieldToCELType resolves the CEL value type for the provided FieldDescriptor. If generic is true, the specific subtypes of map and repeated fields will be replaced with cel.DynType. If forItems is true, the type for the repeated list items is returned instead of the list type itself.

func ProtoFieldToCELValue

func ProtoFieldToCELValue(fieldDesc protoreflect.FieldDescriptor, value protoreflect.Value, forItems bool) ref.Val

func RequiredCELEnvOptions

func RequiredCELEnvOptions(fieldDesc protoreflect.FieldDescriptor) []cel.EnvOption

RequiredCELEnvOptions returns the options required to have expressions which rely on the provided descriptor.

Types

type Lib

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

Lib is the collection of functions and settings required by protovalidate beyond the standard definitions of the CEL Specification:

https://github.com/google/cel-spec/blob/master/doc/langdef.md#list-of-standard-definitions

All implementations of protovalidate MUST implement these functions and should avoid exposing additional functions as they will not be portable.

func (Lib) CompileOptions

func (l Lib) CompileOptions() []cel.EnvOption

func (Lib) ProgramOptions

func (l Lib) ProgramOptions() []cel.ProgramOption
