bitcoin-rest is a Rust library for Bitcoin Core's REST API interface.
All API calls work with rust-bitcoin.
The following example fetches the genesis block and finally the block
variable set to bitcoin::blockdata::block::Block
with the genesis block.
use bitcoin::hash_types::BlockHash;
let rest = bitcoin_rest::new(bitcoin_rest::DEAFULT_ENDPOINT); // or new("http://HOSTNAME:PORT/rest/");
let blockid = BlockHash::from_str("000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f").unwrap();
let block = rest.block(blockid).await.unwrap();
// block.block_hash().to_string() == "000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f"
