Step 1 - define a custom error type This type is a union of all possible error types your program needs to handle: # [derive (Debug)] pub enum MyErrorType { // Errors from external libraries... WebbSearch Tricks. Prefix searches with a type followed by a colon (e.g. fn:) to restrict the search to a given type. Accepted types are: fn, mod, struct, enum, trait, type, macro, and const. Search functions by type signature (e.g. vec -> usize or * -> vec) Search multiple things at once by splitting your query with comma (e.g. str,u8 or String,struct:Vec,test)

WebbThe match arms are returning a value - they have to return the same value. Adding the semi-colon makes that return value () - which is what functions that don't return anything return. That means both arms return () - which is fine.
