There was an unfortunate collision with how test symbols were named and
the various bindings functions exported by wasm-bindgen. This commit
fixes these issues by using a separate prefix for `#[wasm_bindgen_test]`
than other `#[wasm_bindgen]` functions which should avoid the name
clash.
Closes#2121
This commit defaults all crates in-tree to use `std::future` by default
and none of them support the crates.io `futures` 0.1 crate any more.
This is a breaking change for `wasm-bindgen-futures` and
`wasm-bindgen-test` so they've both received a major version bump to
reflect the new defaults. Historical versions of these crates should
continue to work if necessary, but they won't receive any more
maintenance after this is merged.
The movement here liberally uses `async`/`await` to remove the need for
using any combinators on the `Future` trait. As a result many of the
crates now rely on a much more recent version of the compiler,
especially to run tests.
The `wasm-bindgen-futures` crate was updated to remove all of its
futures-related dependencies and purely use `std::future`, hopefully
improving its compatibility by not having any version compat
considerations over time. The implementations of the executors here are
relatively simple and only delve slightly into the `RawWaker` business
since there are no other stable APIs in `std::task` for wrapping these.
This commit also adds support for:
#[wasm_bindgen_test]
async fn foo() {
// ...
}
where previously you needed to pass `(async)` now that's inferred
because it's an `async fn`.
Closes#1558Closes#1695
This is not necessary because references are FFI-safe and compatible with corresponding pointers, so we can just use them directly as an input.
Fixes#1540.
Most of the CLI crates were already in the 2018 edition, and it turns
out that one of the macro crates was already in the 2018 edition so we
may as well move everything to the 2018 edition!
Always nice to remove those `extern crate` statements nowadays!
This commit also does a `cargo fmt --all` to make sure we're conforming
with style again.
