each_variety.rs

1//! network status documents - items for all varieties, that vary
2//!
3//! **This file is reincluded multiple times**,
4//! by the macros in [`crate::doc::ns_variety_definition_macros`],
5//! once for votes, and once for each consensus flavour.
6//! It is *not* a module `crate::doc::netstatus::rs::each_variety`.
7//!
8//! Each time this file is included by one of the macros mentioned above,
9//! the `ns_***` macros (such as `ns_const_name!`) may expand to different values.
10//!
11//! See [`crate::doc::ns_variety_definition_macros`].
