Trait rug::ops::MulFrom

pub trait MulFrom<Lhs = Self> {
    fn mul_from(&mut self, lhs: Lhs);
}

Compound multiplication and assignment to the rhs operand.

rhs.mul_from(lhs) has the same effect as rhs = lhs * rhs.

Examples

use rug::ops::MulFrom;
struct ColumnVec(i32, i32);
struct SquareMatrix(ColumnVec, ColumnVec);
impl<'a> MulFrom<&'a SquareMatrix> for ColumnVec {
    fn mul_from(&mut self, lhs: &SquareMatrix) {
        let SquareMatrix(ref left, ref right) = *lhs;
        let out_0 = left.0 * self.0 + right.0 * self.1;
        self.1 = left.1 * self.0 + right.1 * self.1;
        self.0 = out_0;
    }
}
let mut col = ColumnVec(2, 30);
let matrix_left = ColumnVec(1, -2);
let matrix_right = ColumnVec(3, -1);
let matrix = SquareMatrix(matrix_left, matrix_right);
// ( 1   3) ( 2) = ( 92)
// (−2  −1) (30)   (−34)
col.mul_from(&matrix);
assert_eq!(col.0, 92);
assert_eq!(col.1, -34);

Required methods

fn mul_from(&mut self, lhs: Lhs)

Peforms the multiplication.

Examples

use rug::Integer;
use rug::ops::MulFrom;
let mut rhs = Integer::from(5);
rhs.mul_from(50);
// rhs = 50 × 5
assert_eq!(rhs, 250);
