Expand description

OpenDAL uses Builder to set up a service.

A Builder allows developers to:

Build a service through a builder-style API.
Configure in-memory options, such as customized_credential_load.

Users can usually use the Operator API instead of importing and using Builder directly. For example:

use opendal_core::services::Memory;
use opendal_core::Operator;
async fn test() -> Result<()> {
    // Create a memory backend builder.
    let builder = Memory::default();

    // Build an `Operator` to start operating the storage.
    let op: Operator = Operator::new(builder)?;

    Ok(())
