Rust's Turbofish (`::<>`): When the Compiler Needs Help
The turbofish (`::<>`) is your tool to resolve ambiguity when Rust's compiler can't infer a type or trait. Use it when a type implements multiple traits with same-named methods, forcing the compiler to pick the one you specify.
The turbofish (`::<>`) is your tool to resolve ambiguity when Rust's compiler can't infer the correct type or trait for a method call. It provides a fully-qualified path to a function, essential when a type implements multiple traits with same-named methods. The footgun is not recognizing the "multiple applicable items" error as a signal to use this explicit syntax, instead trying to refactor working code.
