Struct TaskPredictorCore 

pub struct TaskPredictorCore<T>
where
    T: Task,
{ /* private fields */ }

Generic task predictor core.

This struct encapsulates the common pattern used across all predictors: holding an adapter, task instance, and configuration, and executing predictions through the adapter with proper validation.

Type Parameters

• T - The task type that implements the Task trait

Implementations

impl<T> TaskPredictorCore<T>

where T: Task,

pub fn new( adapter: Box<dyn ModelAdapter<Task = T>>, task: T, config: <T as Task>::Config, ) -> TaskPredictorCore<T>

Creates a new task predictor core.

Arguments

• adapter - The model adapter to use for predictions
• task - The task instance for validation
• config - The task configuration

pub fn predict( &self, input: <T as Task>::Input, ) -> Result<<T as Task>::Output, OCRError>

Executes prediction on the given input.

This method performs the complete validation and execution pipeline:

1. Validate input using the task’s validation logic
2. Execute inference through the adapter
3. Validate output using the task’s validation logic

Arguments

• input - The input data for prediction

Returns

The task output on success, or an error if validation or execution fails.

pub fn config(&self) -> &<T as Task>::Config

Returns a reference to the current configuration.

pub fn config_mut(&mut self) -> &mut <T as Task>::Config

Returns a mutable reference to the configuration.

This allows modifying the configuration after the predictor is created, though creating a new predictor with a different configuration is generally preferred for clarity.

pub fn task(&self) -> &T

Returns a reference to the task instance.
