🔧 Advanced Features

Custom Processing Pipelines

use cli_tool::processor::{Pipeline, Processor};

let pipeline = Pipeline::new()
    .add_processor(FilterProcessor::new(|record| record.age > 18))
    .add_processor(TransformProcessor::new(|record| {
        record.name = record.name.to_uppercase();
        record
    }))
    .add_processor(AggregateProcessor::new(|records| {
        // Custom aggregation logic
        records.iter().map(|r| r.value).sum()
    }));

let results = pipeline.process(data).await?;

Plugin System

use cli_tool::plugin::{Plugin, PluginManager};

#[derive(Plugin)]
struct CustomProcessor;

impl Processor for CustomProcessor {
    async fn process(&self, input: Data) -> Result<Data> {
        // Custom processing logic
        Ok(processed_data)
    }
}

// Register plugin
plugin_manager.register(CustomProcessor)?;

Monitoring & Metrics

use cli_tool::metrics::{MetricsCollector, Counter, Histogram};

let metrics = MetricsCollector::new();
let request_counter = metrics.register_counter("requests_total");
let response_time = metrics.register_histogram("response_time_seconds");

// Use in code
request_counter.increment();
let _timer = response_time.start_timer();
