'Go'-Like Interfaces and 'Rust'-Like Traits with 'S7'

v0.1.0 · May 7, 2026 · GPL (>= 3)

Description

Contract helpers built with 'S7' for expressing runtime protocols around ordinary 'S7' dispatch. Structural interfaces describe small sets of required 'S7' generics, while explicit traits record registered implementations with optional default methods and associated metadata. Optional runtime checks can validate argument and return specifications in contract-scoped evaluation.
