Module registry 

crates.io registry client, and the CargoRegistry router dispatching a resolved alternate/private registry to its own crate::sparse::SparseIndexClient.

Provides access to crates.io via:

• Sparse index protocol (https://index.crates.io) for version lookups
• REST API (https://crates.io/api/v1) for search

All HTTP requests are cached aggressively using ETag/Last-Modified headers.

Examples

use deps_cargo::CratesIoRegistry;
use deps_core::HttpCache;
use std::sync::Arc;

#[tokio::main]
async fn main() {
    let cache = Arc::new(HttpCache::new());
    let registry = CratesIoRegistry::new(cache);

    let versions = registry.get_versions("serde").await.unwrap();
    println!("Latest serde: {}", versions[0].num);
}
