Struct bdk::blockchain::rpc::RpcBlockchainFactory

pub struct RpcBlockchainFactory {
    pub url: String,
    pub auth: Auth,
    pub network: Network,
    pub wallet_name_prefix: Option<String>,
    pub default_skip_blocks: u32,
    pub sync_params: Option<RpcSyncParams>,
}

Available on crate feature rpc only.

Factory of RpcBlockchain instances, implements BlockchainFactory

Internally caches the node url and authentication params and allows getting many different RpcBlockchain objects for different wallet names and with different rescan heights.

Example

let factory = RpcBlockchainFactory {
    url: "http://127.0.0.1:18332".to_string(),
    auth: Auth::Cookie {
        file: "/home/user/.bitcoin/.cookie".into(),
    },
    network: Network::Testnet,
    wallet_name_prefix: Some("prefix-".to_string()),
    default_skip_blocks: 100_000,
    sync_params: None,
};
let main_wallet_blockchain = factory.build("main_wallet", Some(200_000))?;

Fields

url: String

The bitcoin node url

auth: Auth

The bitcoin node authentication mechanism

network: Network

The network we are using (it will be checked the bitcoin node network matches this)

wallet_name_prefix: Option<String>

The optional prefix used to build the full wallet name for blockchains

default_skip_blocks: u32

Default number of blocks to skip which will be inherited by blockchain unless overridden

sync_params: Option<RpcSyncParams>

Sync parameters

Trait Implementations

impl BlockchainFactory for RpcBlockchainFactory

type Inner = RpcBlockchain

The type returned when building a blockchain from this factory

fn build( &self, checksum: &str, _override_skip_blocks: Option<u32> ) -> Result<Self::Inner, Error>

Build a new blockchain for the given descriptor wallet_name

fn build_for_wallet<D: BatchDatabase>( &self, wallet: &Wallet<D>, override_skip_blocks: Option<u32> ) -> Result<Self::Inner, Error>

Build a new blockchain for a given wallet

fn sync_wallet<D: BatchDatabase>( &self, wallet: &Wallet<D>, override_skip_blocks: Option<u32>, sync_options: SyncOptions ) -> Result<(), Error>

Available on non-crate feature async-interface only.

Use BlockchainFactory::build_for_wallet to get a blockchain, then sync the wallet

impl Clone for RpcBlockchainFactory

fn clone(&self) -> RpcBlockchainFactory

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RpcBlockchainFactory

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
