func OldMapKeyError(t *abi.OldMapType, punsafe.Pointer)error

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

func (*Iter)Elem¶

func (it *Iter) Elem()unsafe.Pointer

Key returns a pointer to the current element. nil indicates end ofiteration.

Must not be called prior to Next.

func (*Iter)Init¶

func (it *Iter) Init(typ *abi.SwissMapType, m *Map)

Init initializes Iter for iteration.

func (*Iter)Initialized¶

func (it *Iter) Initialized()bool

func (*Iter)Key¶

func (it *Iter) Key()unsafe.Pointer

Key returns a pointer to the current key. nil indicates end of iteration.

Must not be called prior to Next.

func (*Iter)Map¶

func (it *Iter) Map() *Map

Map returns the map this iterator is iterating over.

func (*Iter)Next¶

func (it *Iter) Next()

Next proceeds to the next element in iteration, which can be accessed viathe Key and Elem methods.

The table can be mutated during iteration, though there is no guarantee thatthe mutations will be visible to the iteration.

Init must be called prior to Next.

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

funcNewEmptyMap¶

func NewEmptyMap() *Map

funcNewMap¶

func NewMap(mt *abi.SwissMapType, hintuintptr, m *Map, maxAllocuintptr) *Map

If m is non-nil, it should be used rather than allocating.

maxAlloc should be runtime.maxAlloc.

TODO(prattmic): Put maxAlloc somewhere accessible.

func (*Map)Clear¶

func (m *Map) Clear(typ *abi.SwissMapType)

Clear deletes all entries from the map resulting in an empty map.

func (*Map)Clone¶added ingo1.25.0

func (m *Map) Clone(typ *abi.SwissMapType) *Map

func (*Map)Delete¶

func (m *Map) Delete(typ *abi.SwissMapType, keyunsafe.Pointer)

func (*Map)Get¶

func (m *Map) Get(typ *abi.SwissMapType, keyunsafe.Pointer) (unsafe.Pointer,bool)

Get performs a lookup of the key that key points to. It returns a pointer tothe element, or false if the key doesn't exist.

func (*Map)Put¶

func (m *Map) Put(typ *abi.SwissMapType, key, elemunsafe.Pointer)

func (*Map)PutSlot¶

func (m *Map) PutSlot(typ *abi.SwissMapType, keyunsafe.Pointer)unsafe.Pointer

PutSlot returns a pointer to the element slot where an inserted elementshould be written.

PutSlot never returns nil.

func (*Map)Used¶

func (m *Map) Used()uint64
