bitcoind-cache

A library that helps facilitate storage and retrieval of data produced by bitcoind. Currently supports storing data on a local filesystem, remote http kv-store, and s3-compatible object storage. Currently only supports full blocks and their headers. It probably makes sense to add support for compact blocks and their headers too.

Usage Example

```rust use bitcoin::blockdata::constants::genesis_block; use bitcoin::Network;

use bitcoind_cache::{ store::{AnyStore, FileStore}, BitcoindCache, };

[tokio::main]

async fn main() { let filestore = FileStore::new("bitcoind-store-regtest").expect("path to be created if not exists"); let store = AnyStore::File(filestore); let bitcoind_cache = BitcoindCache::new(Network::Regtest, store);

let genesis_block = genesis_block(Network::Regtest);
let genesis_block_hash = genesis_block.header.block_hash();

// put the genesis block into the cache
if let Err(e) = bitcoind_cache.put_block(&genesis_block).await {
    println!("failed to store block: {:?}", e);
}

// later, read the block out by hash
let block = bitcoind_cache
    .get_block_by_hash(&genesis_block_hash)
    .await
    .expect("to read ok")
    .expect("to be some");

assert_eq!(genesis_block, block);

}
