0.2.16

Released 2018-08-13.

Added

• Added the wasm_bindgen::JsCast trait, as described in RFC #2.
• Added the #[wasm_bindgen(extends = ...)] attribute to describe inheritance relationships, as described in RFC #2.
• Added support for receiving Option<&T> parameters from JavaScript in exported Rust functions and methods.
• Added support for receiving Option<u32> and other option-wrapped scalars.
• Added reference documentation to the guide for every #[wasm_bindgen] attribute and how it affects the generated bindings.
• Published the wasm-bindgen-futures crate for converting between JS Promises and Rust Futures.

Changed

• Overhauled the guide's documentation on passing JS closures to Rust, and Rust closures to JS.
• Overhauled the guide's documentation on using serde to serialize complex data to JsValue and deserialize JsValues back into complex data.
• Static methods are now always bound to their JS class, as is required for Promise's static methods.

Removed

• Removed internal usage of syn's visit-mut cargo feature, which should result in faster build times.

Fixed

• Various usage errors for the #[wasm_bindgen] proc-macro are now properly reported with source span information, rather than panic!()s inside the proc-macro.
• Fixed a bug where taking a struct by reference and returning a slice resulted in lexical variable redeclaration errors in the generated JS glue. #662
• The #[wasm_bindgen(js_class = "....")] attribute for binding methods to renamed imported JS classes now properly works with constructors.

---

0.2.15

Released 2018-07-26.

Fixed

• Fixed wasm-bindgen CLI version mismatch checks that got broken in the last point release.

---

0.2.14

Released 2018-07-25.

Fixed

• Fixed compilation errors on targets that use Mach-O. #545

---

0.2.13

Released 2018-07-22.

Added

• Support the #[wasm_bindgen(js_name = foo)] attribute on exported functions and methods to allow renaming an export to JS. This allows JS to call it by one name and Rust to call it by another, for example using camelCase in JS and snake_case in Rust

Fixed

• Compilation with the latest nightly compiler has been fixed (nightlies on and after 2018-07-21)

---

0.2.12

Released 2018-07-19.

This release is mostly internal refactorings and minor improvements to the existing crates and functionality, but the bigs news is an upcoming js-sys and web-sys set of crates. The js-sys crate will expose all global JS bindings and the web-sys crate will be generated from WebIDL to expose all APIs browsers have. More info on this soon!

Added

• Support for Option<T> was added where T can be a number of slices or imported types.
• Comments in Rust are now preserved in generated JS bindings, as well as comments being generated to indicate the types of arguments/return values.
• The online documentation has been reorganized into a book.
• The generated JS is now formatted better by default for readability.
• A --keep-debug flag has been added to the CLI to retain debug sections by default. This happens by default when --debug is passed.

Fixed

• Compilation with the latest nightly compiler has been fixed (nightlies on and after 2018-07-19)
• Declarations of an imported function in multiple crates have been fixed to not conflict.
• Compilation with #![deny(missing_docs)] has been fixed.
