tear-types 0.1.3

//! Wire-shape mirror of `tear_core::blocks::Block`.
//!
//! Lives in `tear-types` because the daemon's wire layer needs
//! the type but can't depend on `tear-core` (no upward dep —
//! tear-core depends on tear-types). The two crate's `Block`
//! structs share the same serde representation byte-for-byte;
//! we use `From` conversions on the tear-core side to bridge.
