Memory

In memory service support. (BTreeMap Based)

Capabilities

This service can be used to:

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

Example

Via Builder

use std::sync::Arc;

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

#[tokio::main]
async fn main() -> Result<()> {
    let mut builder = Memory::default();
    builder.root("/tmp");

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

    Ok(())
}

Via Config

Rust

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());

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

Node.js

import { Operator } from "opendal";

async function main() {
  const op = new Operator("memory", {
    root: "/path/to/dir",
  });
}

Python

import opendal

op = opendal.Operator("memory",
  root="/path/to/dir",
)
