## Variable sized types
Rust also provides types whose size depends on the size of a pointer of the
underlying machine. These types have ‘size’ as the category, and come in signed
and unsigned varieties. This makes for two types: `isize` and `usize`.
Rust also provides types whose particular size depends on the underlying machine
architecture. Their range is sufficient to express sizes of collections and they
are used to address items in a vector, for example. These types have ‘size’ as
the category, and come in signed and unsigned varieties. This makes for two types:
`isize` and `usize`.
