# Blockpulsar Rust Client
Official Rust client for Blockpulsar API
- Website: https://blockpulsar.com
- API documentation: https://blockpulsar-docs.web.app/
- API version: 1.0.0
- Package version: 1.0.0
## Install
**1.** Edit the generated `Cargo.toml` file to add `blockpulsar_client_rust` as a dependency library:
```
[dependencies]
blockpulsar_client_rust="1.0.0"
```
**2.** Access the library in your code:
```rust
use blockpulsar_client_rust as bp;
```
**3.** Build the project with `cargo build --release`
Cargo will take care of managing the versions, building the dependencies when needed, and passing the correct arguments to the compiler to link together all of the dependencies.
## Example
Set the `api_key` and `secret_key` keys obtaned from the website.
```rust
use blockpulsar_client_rust as bp;
#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
let bp_client = bp::client::BlockpulsarClient::new("api_key", "secret_key");
let bb_hash = bp_client.btc.get_best_block_hash().await;
let block = bp_client.btc.get_block(&bb_hash).await;
println!("{:?}", block);
return Ok(());
}
```
## Methods
```rust

```rust
// Get block header
//
// Args:

get_block_header(block_hash: &str) -> BlockHeader
```
```rust
// Compute per block statistics for a given window. All amounts are in satoshis.
//
// Args:
// -block_hash: The block hash
get_block_stats(block_hash: &str) -> BlockStats
```
```rust
// Return information about all known tips in the block tree, including the main chain
// as well as orphaned branches.
get_chain_tips() -> Vec<ChainTip>
```
```rust
// Compute statistics about the total number and rate of transactions in the chain.
//
// Args:
// -blockhash: (optional) The hash of the block that ends the window. Default is chain tip
// -nblocks: (optional) Size of the window in number of blocks.
get_chain_tx_stats(block_hash: &str, nblocks: u32) -> ChainTxStats
```
```rust
// Returns the proof-of-work difficulty as a multiple of the minimum difficulty.
get_difficulty() -> f64
```
```rust
// Get memory pool ancestors.
//
// Args:
// -txid: The transaction id (must be in mempool)
get_mempool_ancestors(txid: &str) -> Vec<String>
```
```rust
// Get memory pool descendants.
//
// Args:
// -txid: The transaction id (must be in mempool)
get_mempool_descendants(txid: &str) -> Vec<String>
```
```rust
// Returns mempool data for given transaction.
//
// Args:
// -txid: The transaction id (must be in mempool)
get_mempool_entry(txid: &str) -> MempoolEntry
```
```rust
// Returns details on the active state of the transaction memory pool.

get_raw_mempool() -> Vec<String>
```
```rust
// Returns a json object containing mining-related information.
get_mining_info() -> MiningInfo
```
```rust
// Returns the estimated network hashes per second based on the last n blocks.
//
// Args:
// -nblocks: (optional) The number of blocks, or -1 for blocks since last difficulty change.
// -height: (optional) To estimate at the time of the given height.
get_network_hash_ps(nblocks: u32, height: i32) -> u128
```
```rust
// Get raw transaction. When called with a blockhash argument, getrawtransaction will
// return the transaction if the specified block is available and the transaction is found
// in that block.
//
// Args:
// -txid: The transaction ID
// -block_hash: The block in which to look for the transaction.
get_raw_transaction(txid: &str, block_hash: &str) -> RawTransaction
```
