Rust Data Types

This lesson is part of Rust · All levels

Summary

This lesson reviews the statically typed data type system in Rust. Rust has scalar types such as integers, floating-points, booleans, and characters, as well as compound types such as tuple and array. The compiler also has a smart type inference feature to automatically guess the data type.

Key points

Rust is a statically typed language in which all types of variables must be known when compilation
The integer type is available in both marked (i8..i128, isize) and unmarked (u8..u128, usize) variants.
The standard floating-point type includes f32 and f64 (f64 is default)
The 'char' type in Rust is 4 bytes and supports full Unicode characters
