Crate behaviortree_derive 

Derive macros for Behaviors. There are 4 derive macros available:

• Action
• Condition
• Control
• Decorator

On struct level there are the attributes

• #[behavior(no_create)]: will suppress the derive of create_fn(…)
• #[behavior(no_register)]: will suppress the derive of register()
• #[behavior(no_register_with)]: will suppress the derive of register_with(…)

On field level there are the attributes

• #[behavior(parameter)]: defines a field as a parameter for create_fn(...) and register_with(...) The values must be given when using the register_with(...) method. A parameter must implement Clone.
• #[behavior(default = <Expression>)]: defines a default value for a field. ‘Expression’ can be any Rust expression that creates an appropriate value out of nothing.

Usage

#[derive(Action)]

    // specific elements
    ...
}

impl MyAction {
    // your specific implementations
    ...
