Struct StageContext 

pub struct StageContext {
    pub current_image: Arc<RgbImage>,
    pub original_image: Arc<RgbImage>,
    pub image_index: usize,
    pub global_config: HashMap<String, Value>,
    pub stage_results: HashMap<StageId, Box<dyn Any + Send + Sync>>,
}

Context information available to pipeline stages during execution.

Fields

current_image: Arc<RgbImage>

original_image: Arc<RgbImage>

Original input image (before any transformations)

image_index: usize

Index of the current image in batch processing

global_config: HashMap<String, Value>

Global pipeline configuration

stage_results: HashMap<StageId, Box<dyn Any + Send + Sync>>

Results from previous stages
