Lets Learn Rust - 5 - The Integer Data Type

G'day guys

In this video I talk about the integer data type in Rust. I explain both signed an unsigned integers as well as how many bytes each stores, how Rust deals with overflow issues at compile time and much more.

We talk about the following data types specifically:-

- i32 - The default integer type.
- i8
- i16
- i64
- i128
- isize (And how it works for both 32 and 64 bit systems)
- u8
- u16
- u32
- u64
- u128
- usize (Again and how it works for both 32 and 64 bit systems)
