Function update_many 

pub fn update_many<'a, 'b, I, T>(pairs: I)
where
    I: IntoIterator<Item = (&'a mut State, &'b T)>,
    T: 'b + AsRef<[u8]> + ?Sized,

Update any number of State objects at once.

Example

use blake2b_simd::{blake2b, State, many::update_many};

let mut states = [
    State::new(),
    State::new(),
    State::new(),
    State::new(),
];

let inputs = [
    &b"foo"[..],
    &b"bar"[..],
    &b"baz"[..],
    &b"bing"[..],
];

update_many(states.iter_mut().zip(inputs.iter()));

for (state, input) in states.iter_mut().zip(inputs.iter()) {
    assert_eq!(blake2b(input), state.finalize());
}
