Method wasm_binary

crates/wasmtime/src/compile/code_builder.rs:102–118

Configures the WebAssembly binary that is being compiled. The `wasm_bytes` parameter must be a binary WebAssembly file. This will be stored within the [`CodeBuilder`] for processing later when compilation is finalized. The optional `wasm_path` parameter is the path to the `wasm_bytes` on disk, if any. This may be used for diagnostics and other debugging-related purposes, but this method will not
