1//! Entry marker types for the PoH recording pipeline.
2//!
3//! This module defines `EntryOrMarker`, a wrapper type that allows both regular entries and block
4//! markers (headers, footers) to flow through the same PoH recording channel.
5use crate::{block_component::VersionedBlockMarker, entry::Entry};

7/// Wraps either a regular entry or a block metadata marker.
8///
9/// The PoH recorder uses this type to stream both transaction-containing entries and block markers
10/// through a unified channel to downstream consumers, e.g., broadcast stage.
