A Swift API for the Wasmer WebAssembly Runtime.
SwiftyWasmer packages the
Wasmer C API
for the Swift programming language,
i.e. it provides CWasmer system library with a proper module map
and a Wasmer module with a nice Swift style API for Wasmer.
Note: This is for embedding/running WebAssembly (Wasm) modules from within a Swift host program. It is not about compiling Swift to WebAssembly (there is the SwiftWasm effort for this).
What does it look like? Like this:
import Wasmer
// Just load a file into memory
let wasmFile = URL(fileURLWithPath: "sum.wasm")
let wasmData = try Data(contentsOf: wasmFile)
// Compile the Data into a module, and instantiate that
let module = try WebAssembly.Module (wasmData)
let instance = try WebAssembly.Instance(module)
// Run a function exported by the Module
let results = try instance.exports.sum(.i32(7), .i32(8))This package contains the tests for SwiftyWasmer. It is in a separate package because it contains some precompiled Wasm test data that tends to be rather big.
