Methods

impl Operation

fn new(document: &Document) -> Result<Operation>

Try to create a new Operation from a BSON document.

Example

use oplog::Operation;

let document = doc! {
    "ts" => (Bson::TimeStamp(1479561394 << 32)),
    "h" => (-1742072865587022793i64),
    "v" => 2,
    "op" => "i",
    "ns" => "foo.bar",
    "o" => {
        "foo" => "bar"
    }
};
let operation = Operation::new(&document);

Trait Implementations

impl Clone for Operation

fn clone(&self) -> Operation

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)
