//! Primitives of pezkuwi-like chains, that are related to teyrchains functionality.
//!
//! Even though this (bridges) repository references pezkuwi repository, we can't
//! reference pezkuwi crates from pallets. That's because bridges repository is
//! included in the Pezcumulus repository and included pallets are used by Pezcumulus
//! teyrchains. Having pallets that are referencing pezkuwi, would mean that there may
//! be two versions of pezkuwi crates included in the runtime. Which is bad.
