This drops the text format (%.wat) and renames InstantiateModuleFromCode to InstantiateModuleFromBinary as it is no longer ambiguous. We decided to stop supporting the text format as it isn't typically used in production, yet costs a lot of work to develop. Given the resources available and the increased work added with WebAssembly 2.0 and soon WASI 2, we can't afford to spend the time on it. The old parser is used only internally and will eventually be moved to its own repository named watzero, possibly towards archival. See #59 Signed-off-by: Adrian Cole <adrian@tetrate.io>
Allocation examples
The examples in this directory deal with memory allocation concerns in WebAssembly, e.g. How to pass strings in and out of WebAssembly functions.
$ go run greet.go wazero
wasm >> Hello, wazero!
go >> Hello, wazero!
While the below examples use strings, they are written in a way that would work for binary serialization.
- Rust - Calls Wasm built with
cargo build --release --target wasm32-unknown-unknown - TinyGo - Calls Wasm built with
tinygo build -o X.wasm -scheduler=none --no-debug -target=wasi X.go
Note: Each of the above languages differ in both terms of exports and runtime behavior around allocation, because there is no WebAssembly specification for it. For example, TinyGo exports allocation functions while Rust does not. Also, Rust eagerly collects memory before returning from a Wasm function while TinyGo does not.
We still try to keep the examples as close to the same as possible, and highlight things to be aware of in the respective source and README files.
