Function sparse_interp::refpow [−][src]
pub fn refpow<T>(base: &T, exp: usize) -> T where
T: Clone + One + Mul<Output = T> + MulAssign,
Computes base^exp, where the base is a reference and not an owned value.
The number of clones is kept to a minimum. This is useful when objects of type T are large and copying them is expensive.
let x = 10u128; assert_eq!(refpow(&x, 11), 100000000000u128)
