  • stat
  • read
  • write
  • create_dir
  • delete
  • copy
  • rename
  • list
  • presign
  • blocking

Configuration​

  • root: Set the working directory of OpenDAL
  • connection_string: Set the connection string of mongodb server
  • database: Set the database of mongodb
  • collection: Set the collection of mongodb
  • key_field: Set the key field of mongodb
  • value_field: Set the value field of mongodb

Example​

Via Builder​

use anyhow::Result;
use opendal::services::Mongodb;
use opendal::Operator;

#[tokio::main]
async fn main() -> Result<()> {
    let mut builder = Mongodb::default();
    builder.root("/");
    builder.connection_string("mongodb://myUser:myPassword@localhost:27017/myAuthDB");
    builder.database("your_database");
    builder.collection("your_collection");
    // key field type in the table should be compatible with Rust's &str like text
    builder.key_field("key");
    // value field type in the table should be compatible with Rust's Vec<u8> like bytea
    builder.value_field("value");

    let op = Operator::new(builder)?.finish();
    Ok(())
}

Via Config​

use anyhow::Result;
use opendal::Operator;
use opendal::Scheme;
use std::collections::HashMap;

#[tokio::main]
async fn main() -> Result<()> {
    let mut map = HashMap::new();
    map.insert("root".to_string(), "/".to_string());
    map.insert("connection_string".to_string(), "mongodb://myUser:myPassword@localhost:27017/myAuthDB".to_string());
    map.insert("database".to_string(), "your_database".to_string());
    map.insert("collection".to_string(), "your_collection".to_string());
    map.insert("key_field".to_string(), "key".to_string());
    map.insert("value_field".to_string(), "value".to_string());

    let op: Operator = Operator::via_map(Scheme::Mongodb, map)?;
    Ok(())
}
