7//! Utility functions for the plexor-core crate
8
9///
10/// This function takes a generic type T and returns the last part of its type name
11/// by splitting on "::" and taking the last element. This is useful for getting
12/// just the struct name without the full module path.
13///
14/// # Examples
15///
16/// ```
17/// use plexor_core::utils::struct_name_of_type;
18///
19/// struct MyStruct;
20/// assert_eq!(struct_name_of_type::<MyStruct>(), "MyStruct");
21/// ```
