Struct BlockchainReadHandle 

Source 
pub struct BlockchainReadHandle {
    pub pool: Arc<ThreadPool>,
    pub blockchain: Arc<BlockchainDatabase>,
}
Expand description

The [tower::Service] handle to read from the database.

Fields§

§pool: Arc<ThreadPool>

Handle to the custom rayon DB reader thread-pool.

Requests are [rayon::ThreadPool::spawn]ed in this thread-pool, and responses are returned via a channel we (the caller) provide.
