Simple Data Types

Type Family	Types	Examples
Signed Integers	`i8`⮳, `i16`⮳, `i32`⮳, `i64`⮳, `i128`⮳, `isize`⮳.	`-8i8`, `-32i32`.
Unsigned Integers	`u8`⮳, `u16`⮳, `u32`⮳, `u64`⮳, `u128`⮳, `usize`⮳.	`6u8`.
Floating point	`f32`⮳, `f64`⮳.	`0.15`.
Boolean	`bool`⮳.	`true`, `false`.
Unicode Character	`char`⮳	`let z: char = 'ℤ';`
Unit	`unit`⮳.	The `()` type (aka void in other languages) has exactly one value `()`, and is used when there is no other meaningful value that could be returned.
Never	`never`⮳.	`!` represents the type of computations which never resolve to any value at all. For example, the exit function `fn exit(code: i32) -> !` exits the process without ever returning, and so returns `!`.

usize⮳ and isize⮳ are 32 or 64 bits, depending on the architecture of the computer.

Composite Types

Type	Examples
Tuples	`let tup: (i32, f64, u8) = (500, 6.4, 1);`. Access via `let five_hundred = x.0;`. Destructuring via `let (x, y, z) = tup;`.
Arrays	`let a: [i32; 5] = [1, 2, 3, 4, 5];` allocated on the stack. Access via `let first = a[0];`.

A Vector is a similar collection type provided by the standard library that is allowed to grow or shrink in size.

Use the type keyword to declare type aliases: type Kilometers = i32;.

Wrap in all modes with the wrapping_* methods, such as wrapping_add⮳.
Return the std::option::Option::None⮳ value if there is overflow with the checked_* methods.
Return the value and a boolean indicating whether there was overflow with the overflowing_* methods.
Saturate at the value's minimum or maximum values with the saturating_* methods.
