This crate provides a proc macro that rewrites arithemtic operators +,-,* into their saturating equivalents saturating_add, saturating_sub, saturating_mul as well as their assigning versions +=,-=,*=.
The following function for example ````Rust
fn mix(a: u32, b: u32, c: &[u32]) -> u32 {
let mut r = a + b;
for u in c {
r *= u;
}
r
}
is rewritten to
Rust
fn mix(a: u32, b: u32, c: &[u32]) -> u32 {
let mut r = a.saturatingadd(b);
for u in c {
r = r.saturatingmul(u);
}
r
}
