mongodb-ensure-index-rs

Mongoose-style "ensure index" capabilities for the mongodb crate.

Given a desired mongo index definition:

• Create it if it doesn't exist
• Update it when possible if it's changed
• Drop & re-create it in all other cases

Installing

$ cargo add mongodb-ensure-index

Testing

$ make check

Usage

use mongodb::IndexModel;

let index_models = vec![
    {
        IndexModel::builder()
            .keys({
                doc! {"deletedAt": 1}
            })
            .options(Some(
                IndexOptions::builder().name(Some("deletedAt_1".to_string())).build(),
            ))
            .build()
    },
    {
        IndexModel::builder()
            .keys({
                doc! {"email": 1}
            })
            .options(Some({
                // Unique non-null emails
                IndexOptions::builder()
                    .name(Some("email_1".to_string()))
                    .unique(true)
                    .partial_filter_expression({
                        doc! {"email": doc!{"$type": "string"}}
                    })
                    .build()
            }))
            .build()
    },
