witx-async-demo
This is a small demo of witx-bindgen and async functions. The demo
provides a form where a URL to a .tar.gz tarball is input, and the demo will,
from wasm, download, decompress, and extract the file. The file can then be
explored by clicking each of the files.
This is intended to show a number of features of witx-bindgen and interface
types in concert with one another, including:
- Resources - the response/headers objects from the host are resources that wasm
doesn't directly have access to. -
async- thefetchmethod is exposed to wasm as an async method and the
Responsestructure has anasyncmethod for further loading the body. - Nontrivial wasm - the wasm has to parse both the
.gzcontainer and the
.tarformat of the downloaded tarballs, but readily available crates from
crates.io make this easy in Rust.
