crates.io metadata

Parse (and scrap) crates.io to retrieve crate informations & metadata

Scrap (optionnal)

Use feature scrap (uses Reqwest)

use crates_io_metadata::types::CratesIoResponse;

#[tokio::main]
async fn main() -> anyhow::Result<()> {
    let metadata: CratesIoResponse = scrap("tokio").await?;
    Ok(())
}
