Expand description

Core trait for model adapters.

Adapters bridge the gap between task interfaces and concrete model implementations. They handle model-specific preprocessing, inference, and postprocessing while conforming to the task’s typed input/output contract.

Required Associated Types§

Source

type Task: Task

The task type this adapter executes

Required Methods§

Source

fn info(&self) -> AdapterInfo

Returns information about this adapter.

Source

fn execute( &self, input: <Self::Task as Task>::Input, config: Option<&<Self::Task as Task>::Config>, ) -> Result<<Self::Task as Task>::Output, OCRError>

Executes the model on the given input.

This method handles the complete pipeline:

  1. Validate input
  2. Preprocess
  3. Run inference
  4. Postprocess
  5. Validate output
§Arguments
  • input - The task input to process
  • config - Optional configuration for execution
§Returns

The task output or an error

Provided Methods§

Source

fn supports_batching(&self) -> bool

Returns whether this adapter can handle batched inputs efficiently.

Source

fn recommended_batch_size(&self) -> usize

Returns the recommended batch size for this adapter.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
