Configuration​

  • root: Set the work directory for this backend.
  • config_path: Set the configuration path for foundationdb. If not provided, the default configuration path will be used.

You can refer to [FoundationdbBuilder]'s docs for more information

Example​

Via Builder​

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

#[tokio::main]
async fn main() -> Result<()> {
    let mut builder = Foundationdb::default();
    builder.config_path("/etc/foundationdb/foundationdb.conf");

    let op: Operator = 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(), "/path/to/dir".to_string());
    map.insert("config_path".to_string(), "/path/to/config".to_string());

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