* Add support for virtual files (eg, not backed by an OS file). Virtual files are implemented through trait objects, with a default implementation that tries to behave like on-disk files, but entirely backed by in-memory structures. Co-authored-by: Dan Gohman <sunfish@mozilla.com>
This is the wasi-tests crate, which contains source code for the system-level WASI tests.
Building these tests requires that the wasm32-wasi target be installed.
