Struct multiversx_sc::types::CallbackClosureForDeser
source · pub struct CallbackClosureForDeser<M: ManagedTypeApi + ErrorApi> { /* private fields */ }Expand description
Similar object to CallbackClosure, but only used for deserializing from storage
the callback data with the old async call mechanism.
Should not be visible to the developer.
It is a separate type from CallbackClosure, because we want a different representation of the endpoint name.

fn top_decode_or_handle_err<I, H>( top_input: I, h: H ) -> Result<Self, H::HandledErr>where I: TopDecodeInput, H: DecodeErrorHandler,
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.source§fn top_decode<I>(input: I) -> Result<Self, DecodeError>where
I: TopDecodeInput,
fn top_decode<I>(input: I) -> Result<Self, DecodeError>where I: TopDecodeInput,
Attempt to deserialize the value from input.
