Why memory is empty

[kateinoigakukun]

What do you mean "memory is empty"? The parsed module has WasmKit.Memory in memories and WasmKit.DataSegment in data.

Yes, look at the output of WasmKit.Export(name: "memory", descriptor: WasmKit.ExportDescriptor.memory(0))]

[kateinoigakukun]

@996ccs WasmKit.ExportDescriptor.memory(0) means the export entry points to the index 0 of memories

Thank you very much for your reply. Please tell me how to obtain the initializer data in WasmKit.DataSegment. Like this data WasmKit.DataSegment.Active(index: 0, offset: [WasmKit.Instruction.numericConst(I32(1048))], initializer: ArraySlice([2, 0, 0, 0, 22, 0, 0, 0 , 104, 0, 101, 0, 108, 0, 108, 0, 111, 0, 32, 0, 119, 0, 111, 0, 114, 0, 108, 0, 100]))) How do I get initializer.

I don't understand what you are trying to do but you can get the data segment initializer by something like below:

let initializer = switch dataSegment {
case .active(let active): Array(active.initializer)
case .passive(let initializer): initializer
}

I used the code you provided and encountered the same problem myself. The error message 'initializer' is inaccessible due to 'internal' protection level

[kateinoigakukun]

Could you try it again with main branch of WasmKit?

I updated version 0.04, and now the data under the module cannot be accessed. My need is to get the initializer: ArraySlice in WasmParser.DataSegment.active. Can it be exposed? Thanks

[kateinoigakukun]

Ah, sorry. If you just want to extract data segment, you can use WasmParser module directly.

Can you tell me what I should do? Because I am not good at wasmkit and swift development
