Module post_processor 

Post-processing transformations for signal values.

This module provides post-processors that apply transformations to signal values after they have been processed from source data. Post-processors can be used to adjust, normalize, or otherwise transform the values produced by the main processor.

The module provides:

• The PostProcessor enum which represents different post-processing strategies
• Specialized post-processor implementations in submodules
• Error handling for the post-processing operations

Available Post-Processors

The following post-processing strategies are available:

• TickConvertor - Converts values to specific tick sizes

Extensibility

This module is designed to be extensible. New post-processing strategies can be added by:

1. Creating a new post-processor implementation in a submodule
2. Adding a new variant to the PostProcessor enum
3. Implementing the necessary logic in the name and post_process methods

Usage in Registry

Post-processors are used within the registry system to define how signal values should be transformed after the main processing step. Each signal can specify multiple post-processors that are applied in sequence.

Modules

tick

This module provides a post-processor that converts decimal values into tick values based on a logarithmic scale. Tick values represent price points on a non-linear scale, which can be useful for certain financial applications.

Structs

PostProcessError

Error type for post-processor operations.

Enums

PostProcessor

Represents different strategies for post-processing signal values.
