wasm: add wasmtime support #43

Closed abel-von closed 1 year ago

abel-von commented 1 year ago

support wasmtime as the wasm runtime for webassembly sandbox. it use async feature of wasmtime and launch the instance inside the process, without forking a new process. and the limit of memory is supported by wasmtime ResourceLimiter. the cpu limitation of wasmtime is made by a "fuel" machanism and I am not sure how to make it follow the cpu quota limitation of containers. so cpu limitation is still not supported.
