Names and imports

helpers4 is one crate with one module per category. A deliberate consequence is that the same function name can exist in several modules when the operation makes sense for different kinds of data: merging them into one generic function would make the types less precise and the behavior harder to predict.

Importing

Import through the module path, and do not glob-import a module (use helpers4::string::*;): the next name collision would then be yours to debug.

use helpers4::string::capitalize;

assert_eq!(capitalize("hello"), "Hello");

Resolving a conflict

When you need two helpers with the same name in one file, rename at the import site with as, suffixing the module name so the origin stays visible:

use helpers4::string::truncate as truncate_string;

assert_eq!(truncate_string("A very long title", 10, "..."), "A very ...");

The same applies to a name that also exists in the standard library or in another crate you use.
