Expand description

Represents an instantiated, invocable Scrypto module.

Required Methods§

source

fn invoke_export<'r>( &mut self, func_name: &str, args: Vec<Buffer>, runtime: &mut Box<dyn WasmRuntime + 'r> ) -> Result<Vec<u8>, InvokeError<WasmRuntimeError>>

Invokes an export defined in this module.

The expected signature is as follows:

  • The input is a list of U64, each of which represents a (BufferId, BufferLen).
  • The return data is U64, which represents a (SlicePtr, SliceLen).

The return data is copied into a Vec<u8>.
