Functions ¶

func All ¶

func All(typ types.Type, fn func(*types.Term) bool) bool

All is a wrapper for NewTypeSet(typ).All(fn).

func Any ¶

func Any(typ types.Type, fn func(*types.Term) bool) bool

Any is a wrapper for NewTypeSet(typ).Any(fn).

func Callee ¶

func Callee(info *types.Info, call *ast.CallExpr) types.Object

func CoreType ¶

func CoreType(typ types.Type) types.Type

CoreType is a wrapper for NewTypeSet(typ).CoreType()

func Dereference ¶

func Dereference(T types.Type) types.Type

Dereference returns a pointer's element type; otherwise it returns T.

func DereferenceR ¶

func DereferenceR(T types.Type) types.Type

DereferenceR returns a pointer's element type; otherwise it returns T. If the element type is itself a pointer, DereferenceR will be applied recursively.

func FuncName ¶

func FuncName(f *types.Func) string

func IntuitiveMethodSet ¶

func IntuitiveMethodSet(T types.Type, msets *MethodSetCache) []*types.Selection

func IsObject ¶

func IsObject(obj types.Object, name string) bool

func IsPointerLike ¶

func IsPointerLike(T types.Type) bool

IsPointerLike returns true if type T is like a pointer. This returns true for all nillable types, unsafe.Pointer, and type sets where at least one term is pointer-like.

func IsPointerToTypeWithName ¶

func IsPointerToTypeWithName(typ types.Type, name string) bool

func IsSlice ¶

func IsSlice(term *types.Term) bool

func IsTypeName ¶

func IsTypeName(obj *types.TypeName, name string) bool

IsTypeName reports whether obj represents the qualified name. If obj is a type alias, IsTypeName checks both the alias and the aliased type, if the aliased type has a type name.

func IsTypeWithName ¶

func IsTypeWithName(typ types.Type, name string) bool

IsTypeWithName reports whether typ represents a type with the qualified name, If typ is a type alias, IsTypeWithName checks both the alias and the aliased type. The following types can have names: Basic, Named, Alias.

Types ¶

type DeferStack ¶

type DeferStack struct{}

func NewDeferStack ¶

func NewDeferStack() *DeferStack

func (*DeferStack) String ¶

func (t *DeferStack) String() string

func (*DeferStack) Underlying ¶

func (t *DeferStack) Underlying() types.Type

type Field ¶

type Field struct {
	Var  *types.Var
	Tag  string
	Path []int
}

func FlattenFields ¶

func FlattenFields(T *types.Struct) []Field

FlattenFields recursively flattens T and embedded structs, returning a list of fields. If multiple fields with the same name exist, all will be returned.

type Hasher ¶

type Hasher = typeutil.Hasher

func MakeHasher ¶

func MakeHasher() Hasher

type Iterator ¶

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

func NewIterator ¶

func NewIterator(elem types.Type) *Iterator

func (*Iterator) Elem ¶

func (t *Iterator) Elem() types.Type

func (*Iterator) String ¶

func (t *Iterator) String() string

func (*Iterator) Underlying ¶

func (t *Iterator) Underlying() types.Type

type Map ¶

type Map[V any] struct {
	// contains filtered or unexported fields
}

func (*Map[V]) At ¶

func (m *Map[V]) At(key types.Type) (V, bool)

func (*Map[V]) Delete ¶

func (m *Map[V]) Delete(key types.Type) bool

func (*Map[V]) Iterate ¶

func (m *Map[V]) Iterate(f func(key types.Type, value V))

func (*Map[V]) Keys ¶

func (m *Map[V]) Keys() []types.Type

func (*Map[V]) KeysString ¶

func (m *Map[V]) KeysString() string

func (*Map[V]) Len ¶

func (m *Map[V]) Len() int

func (*Map[V]) Set ¶

func (m *Map[V]) Set(key types.Type, value V)

func (*Map[V]) SetHasher ¶

func (m *Map[V]) SetHasher(h typeutil.Hasher)

func (*Map[V]) String ¶

func (m *Map[V]) String() string

type MethodSetCache ¶

type MethodSetCache = typeutil.MethodSetCache

type TypeSet ¶

type TypeSet struct {
	Terms []*types.Term
	// contains filtered or unexported fields
}

func NewTypeSet ¶

func NewTypeSet(typ types.Type) TypeSet

func (TypeSet) All ¶

func (ts TypeSet) All(fn func(*types.Term) bool) bool

All calls fn for each term in the type set and reports whether all invocations returned true. If the type set is empty or unconstrained, All immediately returns false.

func (TypeSet) Any ¶

func (ts TypeSet) Any(fn func(*types.Term) bool) bool

Any calls fn for each term in the type set and reports whether any invocation returned true. It stops after the first call that returned true.

func (TypeSet) CoreType ¶

func (ts TypeSet) CoreType() types.Type

CoreType returns the type set's core type, or nil if it has none. The function only looks at type terms and may thus return core types for some empty type sets, such as 'interface { map[int]string; foo() }'
