Start migrating `wasm_bindgen` tests to `wasm_bindgen_test` (#602) This commit starts migrating the `wasm_bindgen` tests to the `wasm_bindgen_test` framework, starting to assemble the coffin for `wasm-bindgen-test-project-builder`. Over time all of the tests in `tests/all/*.rs` should be migrated to `wasm_bindgen_test`, although they may not all want to go into a monolithic test suite so we can continue to test for some more subtle situations with `#[wasm_bindgen]`. In the meantime those, the `tests/all/api.rs` tests can certainly migrate! 2018-08-01 14:19:19 -05:00			`#![cfg(target_arch = "wasm32")]`

Add an accessor for wasm's own memory as a JS object In addition to closing #495 this'll be useful eventually when instantiating multiple wasm modules from Rust as you'd now be able to acquire a reference to the current module in Rust itself. 2018-08-21 10:42:52 -07:00			`extern crate js_sys;`

Add a `#[wasm_bindgen(start)]` attribute This commit adds a new attribute to `#[wasm_bindgen]`: `start`. The `start` attribute can be used to indicate that a function should be executed when the module is loaded, configuring the `start` function of the wasm executable. While this doesn't necessarily literally configure the `start` section, it does its best! Only one crate in a crate graph may indicate `#[wasm_bindgen(start)]`, so it's not recommended to be used in libraries but only end-user applications. Currently this still must be used with the `crate-type = ["cdylib"]` annotation in `Cargo.toml`. The implementation here is somewhat tricky because of the circular dependency between our generated JS and the wasm file that we emit. This circular dependency makes running initialization routines (like the `start` shim) particularly fraught with complications because one may need to run before the other but bundlers may not necessarily respect it. Workarounds have been implemented for various emission strategies, for example calling the start function directly after exports are wired up with `--no-modules` and otherwise working around what appears to be a Webpack bug with initializers running in a different order than we'd like. In any case, this in theory doesn't show up to the end user! Closes #74 2018-11-28 09:25:51 -08:00			`use wasm_bindgen::prelude::*;`

Implement `JsCast` for all imported types This commit implements the `JsCast` trait automatically for all imported types in `#[wasm_bindgen] extern { ... }` blocks. The main change here was to generate an `instanceof` shim for all imported types in case it's needed.

Allow returning `Result` from functions This commit adds support for exporting a function defined in Rust that returns a `Result`, translating the `Ok` variant to the actual return value and the `Err` variant to an exception that's thrown in JS. The support for return types and descriptors was rejiggered a bit to be a bit more abstract and more well suited for this purpose. We no longer distinguish between functions with a return value and those without a return value. Additionally a new trait, `ReturnWasmAbi`, is used for converting return values. This trait is an internal implementation detail, however, and shouldn't surface itself to users much (if at all). Closes #841 2018-09-17 18:26:45 -07:00			`pub mod rethrow;`
