Variables are immutable by default. This makes Rust safer and makes concurrency easier.
Immutable means once a value is bound to that variable, it cannot be changed.
For example:
fn main() {
let x = 5;
int[][] result; | |
float t, c; | |
float ease(float p) { | |
return 3*p*p - 2*p*p*p; | |
} | |
float ease(float p, float g) { | |
if (p < 0.5) | |
return 0.5 * pow(2*p, g); |
