Module sparse 

Generic sparse-index registry client.

Implements Cargo’s sparse index wire protocol (RFC 2789), shared by crates.io itself and any alternate/private registry declared through .cargo/config.toml. Extracted from registry.rs so crate::registry::CratesIoRegistry and the alternate-registry router (CargoRegistry) both delegate to one implementation instead of duplicating the index-path computation, JSON-lines parsing, and crate-name safety gate.

Examples

use deps_cargo::config::{IndexTrust, RegistryIndex};
use deps_cargo::sparse::SparseIndexClient;
use deps_core::HttpCache;
use deps_core::net_policy::RegistryAccessPolicy;
use std::sync::Arc;

#[tokio::main]
async fn main() {
    let cache = Arc::new(HttpCache::new());
    let policy = RegistryAccessPolicy::default();
    let index = RegistryIndex::new("https://index.crates.io", IndexTrust::Trusted, &policy).unwrap();
    let client = SparseIndexClient::new(index, cache);

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

Structs

SparseIndexClient

Client for one sparse-index registry — crates.io’s own index or an alternate/private one resolved from .cargo/config.toml.
