Module strat 

Built-in ErrorToGodot strategies for mapping Result<T, E> return types of #[func] methods.

This module is intended to be used qualified with strat:: module: strat::Unexpected etc. It is re-exported in the prelude to enable this.

Overview

Each type in this module implements ErrorToGodot with a different mapping strategy. Some strategies are not provided out-of-the-box but could serve as inspiration to build your own. If you find any of those useful, let us know, and we may consider adding them.

Strategy	Mapped type	Ok path	Err path	GDScript ergonomics
strat::Unexpected Unexpected errors	T	val.clone()	Default or failed call	Sees T; ? works with any Error
() Nil on error	Variant	val.to_variant()	null	if val == null
global::Error Godot error enum	global::Error	OK constant	ERR_* constant	val == OK
(not provided) Variant	Variant	val.to_variant()	err.to_variant()	Must check type/value
(not provided) Dictionary ok/err	Dictionary <GString,Variant>	{"ok" => val}	{"err" => msg}	d.has("ok") d["ok"]
(not provided) Array 0/1 elems	Array<T>	[val]	[]	a.is_empty() a.front() – typed!
(not provided) Custom class	Gd<RustResult>	wrap in class	wrap in class	r.is_ok() r.unwrap()
