    // Provided methods
    fn spec(&self) -> &'static CommandSpec { ... }
    fn load<I, S>(&self, args: I) -> Result<ActionInvocation, CommandParseError>

Expand description

Typed Rust equivalent of upstream AbstractCommand.

Upstream command classes bind a concrete action and register a commander callback. In this port the commander callback is represented by load, which parses command-local arguments into the same action invocation shape.
