Struct RandomBuilderSource 

pub struct RandomBuilderSource<TYPES: NodeType> {
    blocks: Arc<RwLock<LruCache<BuilderCommitment, BlockEntry<TYPES>>>>,
    pub_key: TYPES::BuilderSignatureKey,
    num_nodes: Arc<RwLock<usize>>,
    should_fail_claims: Arc<AtomicBool>,
}

A mock implementation of the builder data source. Builds random blocks, doesn’t track HotShot state at all. Evicts old available blocks if HotShot doesn’t keep up.

Fields

blocks: Arc<RwLock<LruCache<BuilderCommitment, BlockEntry<TYPES>>>>

Built blocks

pub_key: TYPES::BuilderSignatureKey

num_nodes: Arc<RwLock<usize>>

should_fail_claims: Arc<AtomicBool>
