Method wrap

crates/wasmtime/src/runtime/func.rs:809–819

Creates a new `Func` from the given Rust closure. This function will create a new `Func` which, when called, will execute the given Rust closure. Unlike [`Func::new`] the target function being called is known statically so the type signature can be inferred. Rust types will map to WebAssembly types as follows: | Rust Argument Type | WebAssembly Type | |---

(
        store: impl AsContextMut<Data = T>,
        func: impl IntoFunc<T, Params, Results>,
    )

    /// # }
    /// ```
    pub fn wrap<T, Params, Results>(
        store: impl AsContextMut<Data = T>,
        func: impl IntoFunc<T, Params, Results>,
    ) -> Func
    where
        T: 'static,
    {
        Self::try_wrap(store, func).expect(
            "allocation failure during `Func::wrap` (use `Func::try_wrap` to handle such errors)",
        )
    }

    /// Fallible version of [`Func::wrap`] that returns an error on
    /// out-of-memory instead of panicking.
