Trait rug::ops::ShrFrom
[−]
[src]
pub trait ShrFrom<Lhs = Self> {
fn shr_from(&mut self, lhs: Lhs);
}Compound right shift and assignment to the rhs operand.
rhs.shr_from(lhs) has the same effect as rhs = lhs >> rhs.
Examples
use rug::Integer; use rug::ops::ShrFrom; use std::mem; struct I(Integer); impl ShrFrom for I { fn shr_from(&mut self, mut lhs: I) { let rhs = self.0.to_i32().expect("overflow"); mem::swap(self, &mut lhs); self.0 >>= rhs; } } let mut i = I(Integer::from(4)); i.shr_from(I(Integer::from(0xf000))); let expected = Integer::from(0xf000) >> 4; assert_eq!(i.0, expected);
Required Methods
fn shr_from(&mut self, lhs: Lhs)
Peforms the right shift.
Examples
use rug::ops::ShrFrom; let mut rhs = 4; rhs.shr_from(0x00f0); // rhs = 0x00f0 >> 4 assert_eq!(rhs, 0x000f);
