Provided methods

fn start_index(&self) -> Option<u64>

Fetch the start_index of the current object

use activitystreams::prelude::*;

if let Some(start_index) = collection.start_index() {
    println!("{:?}", start_index);
}

fn set_start_index<T>(&mut self, start_index: T) -> &mut Self where
    T: Into<u64>, 

Set the start_index for the current object

This overwrites the contents of start_index

use activitystreams::prelude::*;

collection.set_start_index(5u64);

fn take_start_index(&mut self) -> Option<u64>

Take the start_index of the current object, leaving nothing

use activitystreams::prelude::*;

if let Some(start_index) = collection.start_index() {
    println!("{:?}", start_index);
}

fn delete_start_index(&mut self) -> &mut Self

Delete the start_index from the current object

use activitystreams::prelude::*;

assert!(collection.start_index().is_some());
collection.delete_start_index();
assert!(collection.start_index().is_none());
