Method hint

crates/wasmtime/src/compile/code_builder.rs:734–743

Returns a hint, if possible, of what the provided bytes are. This method can be use to detect what the previously supplied bytes to methods such as [`CodeBuilder::wasm_binary_or_text`] are. This will return whether a module or a component was found in the provided bytes. This method will return `None` if wasm bytes have not been configured or if the provided bytes don't look like either a compon
