rustHow do I declare a constant in Rust?

Constants in Rust are declared using the const keyword. The value of a constant must be known at compile time, and it cannot be changed once declared.

Example

const MAX_POINTS: u32 = 100_000;

This declares a constant named MAX_POINTS of type u32 with a value of 100_000.

Code explanation

• const: keyword used to declare a constant
• MAX_POINTS: name of the constant
• u32: type of the constant
• 100_000: value of the constant
