pub struct ArgDecodeInput<AA>where
AA: ManagedTypeApi + EndpointArgumentApi,{ /* private fields */ }Expand description
Adapter from the API to the TopDecodeInput trait. Allows objects to be deserialized directly from the API as arguments.
Of course the implementation provides shortcut deserialization computation paths directly from API: into_u64, into_i64, …
This is a performance-critical struct. Since the wasm EndpointArgumentApi (VmApiImpl) is zero-size, it means that this structures translates to a single glorified i32 in wasm.
