Implicit Go interfaces versus explicit Rust trait impls
WHAT IT TESTS: understanding of conformance models and maintainability. OUTLINE: Go's implicit satisfaction enables decoupling and retrofitting but hides who implements what and risks accidental conformance; Rust's explicit impls aid discovery, refactoring…
WHAT IT TESTS: whether you can articulate how implicit versus explicit conformance affects real maintenance. ANSWER OUTLINE: Go interfaces are satisfied by any type with matching methods, with no declaration. This decouples packages and lets you define interfaces after the fact, but makes it hard to discover all implementers, allows accidental conformance, and means a method-signature change silently breaks conformance far away.
