Add support for `#[wasm_bindgen(readonly)]` which indicates that an exported
struct field is readonly and attempting to set it in JS will throw an exception.
Closes#151
Automatically infer public struct fields as "JS wants to access this" and
generate appropriate getters/setters for the field. At this time the field is
required to implement `Copy`, but we will probably want to relax that in the
future to at least encompass `JsValue` and maybe other `Clone` values as well.
Closes#121
Currently the entire `Program` is deserialized to match schema versions but this
is likely to fail when the schema changes. Instead just deserialize the
schema/version fields, compare those, and if successful go ahead and deserialize
everything.
This commit adds support for both `#![no_std]` in the wasm-bindgen runtime
support (disabled by default with an on-by-default `std` feature). This also
adds support to work and compile in the context of `#![no_std]` crates.
Closes#146
This commit adds support for closures with arguments like strings and such. In
other words, closures passed to JS can now have the same suite of arguments as
all functions that can be exported from Rust, as one might expect!
At this time due to the way trait objects work closures still cannot use types
with references like `&str`, but bare values like `String` or `ImportedType`
should work just fine.
Closes#104
This commit overhauls the conversion traits used for types crossing the Rust/JS
boundary. Previously there were a few ad-hoc traits but now there've been
slightly reduced and decoupled.
Conversion from Rust values to JS values is now exclusively done through
`IntoWasmAbi` with no special treatment for references. Conversion from JS to
Rust is a bit trickier as we want to create references in Rust which have
implications in terms of safety. As a result there are now three traits for
this, `FromWasmAbi`, `RefFromWasmAbi`, and `RefMutFromWasmAbi`. These three
traits are implemented for various types and specially dispatched to depending
on the type of argument in the code generator.
The goal of this commit is to lay the groundwork for using these traits in
closures with straightforward-ish definitions.
This commit adds support for passing `&mut FnMut(..)` to JS via imports. These
closures cannot be invoked recursively in JS (they invalidate themselves while
they're being invoked) and otherwise work the same as `&Fn(..)` closures.
Closes#123
