Trait ScriptRet 

pub trait ScriptRet {
    // Required methods
    fn script_ty() -> ScriptTy;
    fn into_script_result(self) -> ScriptResult;
}

What a ScriptFn::from_fn closure may return: a value, or a Result whose error message reaches the script.

The declared return type is T either way, so the same declaration binds a closure that can fail and one that cannot.

Required Methods

fn script_ty() -> ScriptTy

The declared return type.

fn into_script_result(self) -> ScriptResult

The result the body hands the host.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
