pub struct Index { /* private fields */ }
Expand description
Specify field to be used for indexing and options.
Example
use mongodm::{Index, SortOrder, IndexOption, mongo::bson::doc};
let index = Index::new_with_direction("username", SortOrder::Descending)
.with_key("last_seen") // compound with last_seen
.with_option(IndexOption::Unique);
let doc = index.into_document();
assert_eq!(
doc,
doc! {
"key": { "username": -1, "last_seen": 1 },
"unique": true,
"name": "username_-1_last_seen_1",
}
)
