Struct CrawlerConfig 

pub struct CrawlerConfig {
    pub max_concurrent_downloads: usize,
    pub parser_workers: usize,
    pub max_concurrent_pipelines: usize,
    pub channel_capacity: usize,
}

Core configuration for the crawler’s concurrency settings.

This struct holds tunable parameters that control the parallelism and throughput of the crawler.

Fields

The maximum number of concurrent downloads.

parser_workers: usize

The number of workers dedicated to parsing responses.

max_concurrent_pipelines: usize

The maximum number of concurrent item processing pipelines.

channel_capacity: usize

The capacity of communication channels between components.
