Trait Builder 

pub trait Builder: Default + 'static {
    type Config: Configurator;

    // Required method
    fn build(self) -> Result<impl Access>;
}

Builder is used to set up underlying services.

This trait allows the developer to define a builder struct that can:

• build a service via builder style API.
• configure in-memory options like http_client or customized_credential_load.

Usually, users don’t need to use or import this trait directly, they can use Operator API instead.

For example:

use opendal::services::Fs;
use opendal::Operator;
async fn test() -> Result<()> {
    // Create fs backend builder.
    let mut builder = Fs::default().root("/tmp");

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

    Ok(())
}

Required Associated Types

type Config: Configurator

Associated configuration for this builder.

Required Methods

fn build(self) -> Result<impl Access>

Consume the accessor builder to build a service.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
