Method func_wrap

crates/wasmtime/src/runtime/linker.rs:560–570

Define a host function within this linker. For information about how the host function operates, see [`Func::wrap`]. That includes information about translating Rust types to WebAssembly native types. This method creates a host-provided function in this linker under the provided name. This method is distinct in its capability to create a [`Store`](crate::Store)-independent function. This means t
