In this case the memory in the env you are passing will be ignored. you can see with wasm objdump if this is the case. what tools are you using to build your module. if you are linking with wasm ld you can pass import memory to the linker if you want memory to be imported.

Github Chai2010 Wasm Book Code Webassembly标准入门 代码 Both webassembly and javascript can create memory objects. if you want to access the memory created in js from webassembly, or vice versa, you can export the memory from the module to javascript or import memory from javascript to the module when it is instantiated. If a wasm has been built without memory growth, the imported memory must be identical in size to it. if the size is too big, you'll get linkerror: imported memory with incompatible size. From the javascript side, one memory can be provided (imported) to the webassembly module. this is demonstrated with the following wat program of a fibonacci algorithm. the interpretation. For other javascript functions imported into assemblyscript we need to define them before they can be imported. to define a custom import in assemblyscript we declare it's function signature. here we're defining a log function that will allow us to call console.log() from web assembly code.

In this article we explore using memory in webassembly in various scenarios passing javascript arrays to rust and assemblyscript modules, checking for some basic memory leaks using valgrind, or exchanging strings between runtimes and modules using wasmtime. Understanding the memory model of webassembly will be important in order to fully comprehend its power as well as its constraints. a typical demo of c c targeting webassembly is a simple function, with primitive inputs and output. In this post, i am playing around with emscipten. it is a wasm compiler which wraps around clang to compile c c source code in a binary .wasm format. it also provides some glue code api to embed this wasm binary into javascript. just look into mdn docs and emscripten sdk to get started. When i was looking into how to use webassembly (wasm), i kept asking myself: how can i pass my variables back and forth from the wasm module? while you can pass some primitives back and forth quite easily, i was a bit confused about how things like arrays could be passed to and from the wasm.
