Usized
Usized refers to a concept in Rust programming related to integer types that have a size determined by the target architecture. Unlike fixed-size integers like `i32` or `u64`, `usize` and `isize` are platform-dependent. On a 32-bit system, `usize` is equivalent to `u32`, and on a 64-bit system, it is equivalent to `u64`. The same applies to `isize` and its signed counterparts.
The primary use case for `usize` is indexing into collections such as arrays, vectors, and strings. This
Similarly, `isize` is used for quantities that can be negative, such as offsets or differences in indices.
