Functions ¶
func IsJsObject ¶
func IsJsPackage ¶
func OffsetOf ¶ added in v1.20.0
OffsetOf returns byte offset of a struct field specified by the provided selection.
Adapted from go/types.Config.offsetof().
func RecvAsFirstArg ¶ added in v1.20.0
RecvAsFirstArg takes a method signature and returns a function signature with receiver as the first parameter.
Types ¶
type Map ¶ added in v1.20.0
type Map[Val any] struct { // contains filtered or unexported fields }
Map is a type-safe wrapper around golang.org/x/tools/go/types/typeutil.Map.
type Selection ¶ added in v1.20.0
type Selection interface {
Kind() types.SelectionKind
Recv() types.Type
Index() []int
Obj() types.Object
Type() types.Type
}
Selection is a common interface for go/types.Selection and our custom-constructed method and field selections.
type Signature ¶ added in v1.20.0
Signature is a helper that provides convenient access to function signature type information.
func (Signature) HasNamedResults ¶ added in v1.20.0
HasNamedResults returns true if the function signature returns something and returned results are names (e.g. `func () (val int, err error)`).
func (Signature) HasResults ¶ added in v1.20.0
HasResults returns true if the function signature returns something.
func (Signature) Param ¶ added in v1.20.0
Param returns the expected argument type for the i'th argument position.
This function is able to return correct expected types for variadic calls both when ellipsis syntax (e.g. myFunc(requiredArg, optionalArgSlice...)) is used and when optional args are passed individually.
The returned types may differ from the actual argument expression types if there is an implicit type conversion involved (e.g. passing a struct into a function that expects an interface).
func (Signature) RequiredParams ¶ added in v1.20.0
RequiredParams returns the number of required parameters in the function signature.
func (Signature) VariadicType ¶ added in v1.20.0
VariadicType returns the slice-type corresponding to the signature's variadic parameter, or nil of the signature is not variadic. With the exception of the special-case `append([]byte{}, "string"...)`, the returned type is `*types.Slice` and `.Elem()` method can be used to get the type of individual arguments.
type TypeList ¶ added in v1.20.0
TypeList an ordered list of types.
type TypeNames ¶ added in v1.20.0
type TypeNames struct {
// contains filtered or unexported fields
}
TypeNames implements an ordered set of *types.TypeName pointers.
The set is ordered to ensure deterministic behavior across compiler runs.
