Crate behaviortree_derive

Expand description

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

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(…)
#[behavior(groot2)]: marks the behavior as one that is internally known to Groot2

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.
#[behavior(parameter, default = <Expression>)]: combines both. The field is a parameter of create_fn(...) and register_with(...), and ‘Expression’ provides the value that the parameterless register() passes for it instead of Default::default().
#[behavior(portlist)]: marks the field that holds the behavior’s port list. This attribute cannot be combined with any other attribute.

Fields without any of these attributes are initialised with Default::default().

§Usage

Example uses the derive macro Action, the others work respectively.

#[derive(Action)]
struct MyAction {
    // specific elements
    ...
}

impl MyAction {
    // your specific implementations
    ...
}
