Error

A cyclic dependency error in Rust occurs when two modules or crates depend on each other, preventing the compiler from resolving types. To fix this, refactor your code to extract the shared types or traits into a separate, third module that both original modules can depend on without depending on each other. For example, if module_a and module_b are cyclic, create module_shared, move the common definitions there, and have both module_a and module_b use items from module_shared instead of each other.

The "cyclic dependency detected" error happens when two parts of your code try to use each other at the same time, creating a loop the compiler can't solve. Think of it like two people trying to hold each other's hands while standing back-to-back; neither can move forward. You fix it by having them both hold hands with a third person standing in the middle, breaking the direct loop.
