Trait Tasklet

Source

pub trait Tasklet {
    // Required method
    fn execute(
        &self,
        step_execution: &StepExecution,
    ) -> Result<RepeatStatus, BatchError>;
}

Expand description

A tasklet represents a single task or operation that can be executed as part of a step.

Tasklets are useful for operations that don’t fit the chunk-oriented processing model, such as file operations, database maintenance, or custom business logic.

§Examples

use spring_batch_rs::core::step::{StepExecution, RepeatStatus};
use spring_batch_rs::BatchError;

use spring_batch_rs::core::step::Tasklet;

struct FileCleanupTasklet {
    directory: String,
}

impl Tasklet for FileCleanupTasklet {
    fn execute(&self, _step_execution: &StepExecution) -> Result<RepeatStatus, BatchError> {
        // Perform file cleanup logic here
        println!("Cleaning up directory: {}", self.directory);
        Ok(RepeatStatus::Finished)
    }
}
