//! Block-details pipe wiring.
//!
//! # Components
//!
//! - [`BlockDetailsPipe`] — internal pipe wrapping the user processor and
//!   filters for `Update::BlockDetails`. Constructed by
//!   `PipelineBuilder::block_details(...)` and
//!   `block_details_with_filters(...)`.
//! - [`BlockDetailsPipes`] — dyn-dispatch trait the pipeline holds as `Box<dyn
//!   BlockDetailsPipes>`.
