//! Account-deletion pipe wiring.
//!
//! # Components
//!
//! - [`AccountDeletionPipe`] — internal pipe wrapping the user processor and
//!   filters for `Update::AccountDeletion`. Constructed by
//!   `PipelineBuilder::account_deletions(...)` and
//!   `account_deletions_with_filters(...)`.
//! - [`AccountDeletionPipes`] — dyn-dispatch trait the pipeline holds as
//!   `Box<dyn AccountDeletionPipes>`.
