Struct Fallback 

pub struct Fallback { /* private fields */ }

Control node that tries children in order until one succeeds.

Fallback ticks children in order on each tick:

• returns TickStatus::Success as soon as a child succeeds
• returns TickStatus::Running as soon as a child is still running
• returns TickStatus::Failure only if every child fails on the same tick

This variant does not remember which child was previously running, so the next tick starts again from the first child.

impl Node for Fallback

fn tick(&mut self) -> TickStatus

Interface to abort/cancel running tasks. Signal is generated by scheduling (non-leaf) nodes and propagated to children. If leaf node’s task is running in an executor an abort signal is sent.

fn reset(&mut self)
