fn transmute_from_handle_ref(handle_ref: &M::ManagedBufferHandle) -> &Self

Implement carefully, since the underlying transmutation is an unsafe operation. For types that wrap a handle to some VM-managed data, make sure the type only contains the handle (plus ZSTs if necessary). For types that just wrap another managed type it is easier, call for the wrapped object.

Version of dep_decode that can handle errors as soon as they occur. For instance in can exit immediately and make sure that if it returns, it is a success. By not deferring error handling, this can lead to somewhat smaller bytecode.

where O: NestedEncodeOutput, H: EncodeErrorHandler,

Version of dep_encode that can handle errors as soon as they occur. For instance in can exit immediately and make sure that if it returns, it is a success. By not deferring error handling, this can lead to somewhat smaller bytecode.

Version of top_decode that can handle errors as soon as they occur. For instance it can exit immediately and make sure that if it returns, it is a success. By not deferring error handling, this can lead to somewhat smaller bytecode.

fn top_decode<I>(input: I) -> Result<Self, DecodeError>
where I: TopDecodeInput,

Attempt to deserialize the value from input.

where O: TopEncodeOutput, H: EncodeErrorHandler,

Version of top_encode that can handle errors as soon as they occur. For instance in can exit immediately and make sure that if it returns, it is a success. By not deferring error handling, this can lead to somewhat smaller bytecode.

where O: TopEncodeOutput,

fn push_single_value<T, H>( &mut self, arg: &T, h: H, ) -> Result<(), H::HandledErr>
where T: TopEncode, H: EncodeErrorHandler,

fn push_multi_specialized<T, H>( &mut self, _arg: &T, h: H, ) -> Result<(), <H as EncodeErrorHandler>::HandledErr>
where T: TryStaticCast, H: EncodeErrorHandler,

This is temporary, will remove after we get rid of SCResult for good.

impl<M> TypeAbi for ManagedArgBuffer<M>
where M: ManagedTypeApi,

fn type_name() -> TypeName

It is semantically equivalent to any list of T.

type Unmanaged = ArgBuffer

fn type_name_rust() -> TypeName

fn type_names() -> TypeNames

fn provide_type_descriptions<TDC: TypeDescriptionContainer>( accumulator: &mut TDC, )

A type can provide more than its own name. For instance, a struct can also provide the descriptions of the type of its fields. TypeAbi doesn’t care for the exact accumulator type, which is abstracted by the TypeDescriptionContainer trait.
