In Rust, we have various data types that represent numbers, truth values, characters, and more. In this lesson, we will focus on i32, f32, bool, char, and String.
The i32 data type represents 32-bit integers. The maximum value an i32 can store is 2147483647, or , and the minimum is -2147483648, or . Here's an example of i32:
Next, we have the f32 data type in Rust, used for floating-point numbers — that is, numbers with decimal points. It can contain up to 7 decimal digits:
Beyond numbers, we have the bool data type, which can hold either true or false. This type is commonly used in logical expressions and decision making:
We also have the char data type. This type is used to represent single Unicode character. char variables must be surrounded by single quotes (')
Last but not least, we have String. String is used to store a sequence of char elements.
There are two types of Strings in Rust.
String literals are immutable and have a type of &str.
On the other hand, a String is by default immutable, but can be made mutable using the mut keyword.
Excellent! You've just explored the basic data types in Rust. You can now handle i32 and f32 for numerical operations, bool for decision-making, char to manage characters, and String to work with textual data.
That's a significant amount of new knowledge! Let's consolidate it through practice. The upcoming exercises are designed to help you apply these concepts. Brace yourself, and get ready to dive deeper into the world of Rust!
