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
.
