Trait FoodInjectionTrait

pub trait FoodInjectionTrait {
    // Required method
    fn inject_food(
        &mut self,
        feed_channels: &mut FeedChannels,
        feedpattern: &Feedpattern,
    ) -> (bool, Result<(), Vec<FoodInjectionError>>);
}

Trait for the execution of the feed pattern. This trait allows running the main control with a mock implementation for testing.

Required Methods

fn inject_food( &mut self, feed_channels: &mut FeedChannels, feedpattern: &Feedpattern, ) -> (bool, Result<(), Vec<FoodInjectionError>>)

Actuates the feeder according to the specified feed pattern to inject food.

This trait method defines the interface for physically dispensing food based on a detailed feed pattern. Implementations will control relevant pumps and the feeder motor through communication with a hardware manager (e.g., relay manager), while also monitoring for external shutdown commands.

Arguments

• feed_channels - A mutable reference to the struct containing the channels.
• feed_pattern - A reference to the struct holding the description of the feed pattern.

Returns

A tuple (bool, Result<(), Vec<FoodInjectionError>>) where:

• The first element (bool) is true if a Quit command was received from the signal handler, indicating an early termination request. Otherwise, it is false.
• The second element is a Result. It is Ok(()) if the entire sequence is completed without any errors.

Errors

The Result part of the return tuple will be Err(Vec<FoodInjectionError>) if one or more errors occurred during the process. The vector will contain all errors encountered, which can include:

• Communication failures with the relay manager (RelayManagerSend, RelayManagerReceive).
• An attempt to set a device to an undefined state (e.g., UndefinedTargetStateSkimmer).
