bitcoind-cache

一个帮助简化由bitcoind生成的数据存储和检索的库。目前支持在本地文件系统、远程http kv存储和s3兼容对象存储上存储数据。目前仅支持完整块及其头部。也许还应该添加对紧凑块及其头部的支持。

使用示例

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);
}
