What is the u32::MIN constant in Rust?
Overview
The u32 stands for 32-bit unsigned integer type. It is an unsigned integer because it cannot contain a negative value like signed integers. The range of u32 is 0 to 4294967295. In order to get the smallest value of this integer type, we must use the MIN constant.
Syntax
u32::MIN
syntax for MIN constant in Rust
Parameters
This method requires no parameter.
Return value
This method returns the value 0 .
Code example
Let's look at the code below:
fn main() {// print the MIN constantprintln!("{}", u32::MIN);// perform some operations with itprintln!("{}", u32::MIN + 1);println!("{}", u32::MIN / 1 + 10);println!("{}", u32::MIN + 500 - 100);println!("{}", u32::MIN * 78);}
Code explanation
- Line 3: We print the
MINconstant. - Lines 6 to 9: We perform some arithmetic operations using the
MINconstant of theu32and print the results to the console.
