| <p>OpenDAL’s development is guided by its vision of <strong>One Layer, All Storage</strong> and its core principles: <strong>Open Community</strong>, <strong>Solid Foundation</strong>, <strong>Fast Access</strong>, <strong>Object Storage First</strong>, and <strong>Extensible Architecture</strong>. Read the explained vision at <a href="https://opendal.apache.org/vision">OpenDAL Vision</a>.</p> |
| <h2 id="quick-start"><a class="doc-anchor" href="#quick-start">§</a>Quick Start</h2> |
| <p>OpenDAL’s API entry points are <a href="struct.Operator.html" title="struct opendal_core::Operator"><code>Operator</code></a> and <a href="blocking/struct.Operator.html" title="struct opendal_core::blocking::Operator"><code>blocking::Operator</code></a>. All |
| public APIs are accessible through the operator. To utilize OpenDAL, you |
| need to:</p> |

| <li><a href="#compose-layers">Compose layers</a></li> |
| <li><a href="#use-operator">Use operator</a></li> |
| </ul> |
| <h3 id="init-a-service"><a class="doc-anchor" href="#init-a-service">§</a>Init a service</h3> |
| <p>The first step is to pick a service and init it with a builder. All supported |
| services could be found at <a href="services/index.html" title="mod opendal_core::services"><code>services</code></a>.</p> |
| <p>Let’s take <a href="services/struct.Memory.html" title="struct opendal_core::services::Memory"><code>services::Memory</code></a> as an example:</p> |
| |
| <div class="example-wrap"><pre class="rust rust-example-rendered"><code><span class="kw">use </span>opendal_core::services; |
| <span class="kw">use </span>opendal_core::Operator; |
| <span class="kw">use </span>opendal_core::Result; |
| |
| <span class="kw">fn </span>main() -> <span class="prelude-ty">Result</span><()> { |
| <span class="comment">// Pick a builder and configure it. |
| </span><span class="kw">let </span>builder = services::Memory::default(); |
| |
| <span class="comment">// Init an operator |
| </span><span class="kw">let </span>op = Operator::new(builder)<span class="question-mark">?</span>.finish(); |
| <span class="prelude-val">Ok</span>(()) |
| }</code></pre></div><h3 id="compose-layers"><a class="doc-anchor" href="#compose-layers">§</a>Compose layers</h3> |
| <p>The next setup is to compose layers. Layers are modules that provide extra |
| features for every operation. All builtin layers could be found at <a href="layers/index.html" title="mod opendal_core::layers"><code>layers</code></a>.</p> |
| <p>Let’s use <a href="layers/struct.HttpClientLayer.html" title="struct opendal_core::layers::HttpClientLayer"><code>layers::HttpClientLayer</code></a> as an example; this layer allows |
| customizing the HTTP client used by OpenDAL.</p> |
| |
| <div class="example-wrap"><pre class="rust rust-example-rendered"><code><span class="kw">use </span>opendal_core::layers::HttpClientLayer; |
| <span class="kw">use </span>opendal_core::raw::HttpClient; |

| <span class="kw">use </span>opendal_core::Operator; |
| <span class="kw">use </span>opendal_core::Result; |
| |
| <span class="attr">#[tokio::main] |
| </span><span class="kw">async fn </span>main() -> <span class="prelude-ty">Result</span><()> { |
| <span class="comment">// Pick a builder and configure it. |

| <span class="kw">let </span>op = Operator::new(builder)<span class="question-mark">? |
| </span><span class="comment">// Init with custom HTTP client. |
| </span>.layer(HttpClientLayer::new(client)) |
| .finish(); |
| |
| <span class="prelude-val">Ok</span>(()) |
| }</code></pre></div><h3 id="use-operator"><a class="doc-anchor" href="#use-operator">§</a>Use operator</h3> |
| <p>The final step is to use the operator. OpenDAL supports both async <a href="struct.Operator.html" title="struct opendal_core::Operator"><code>Operator</code></a> |
| and blocking <a href="blocking/struct.Operator.html" title="struct opendal_core::blocking::Operator"><code>blocking::Operator</code></a>. Please pick the one that fits your use case.</p> |
| <p>Every Operator API follows a consistent pattern. For example, consider the <code>read</code> operation:</p> |
| <ul> |
| <li><a href="struct.Operator.html#method.read" title="method opendal_core::Operator::read"><code>Operator::read</code></a>: Executes a read operation.</li> |
| <li><a href="struct.Operator.html#method.read_with" title="method opendal_core::Operator::read_with"><code>Operator::read_with</code></a>: Executes a read operation with additional options using the builder pattern.</li> |
| <li><a href="struct.Operator.html#method.read_options" title="method opendal_core::Operator::read_options"><code>Operator::read_options</code></a>: Executes a read operation with extra options provided via a <a href="options/struct.ReadOptions.html" title="struct opendal_core::options::ReadOptions"><code>options::ReadOptions</code></a> struct.</li> |
| <li><a href="struct.Operator.html#method.reader" title="method opendal_core::Operator::reader"><code>Operator::reader</code></a>: Creates a reader for streaming data, allowing for flexible access.</li> |
| <li><a href="struct.Operator.html#method.reader_with" title="method opendal_core::Operator::reader_with"><code>Operator::reader_with</code></a>: Creates a reader with advanced options using the builder pattern.</li> |
| <li><a href="struct.Operator.html#method.reader_options" title="method opendal_core::Operator::reader_options"><code>Operator::reader_options</code></a>: Creates a reader with extra options provided via a <a href="options/struct.ReadOptions.html" title="struct opendal_core::options::ReadOptions"><code>options::ReadOptions</code></a> struct.</li> |
| </ul> |
| <p>The <a href="struct.Reader.html" title="struct opendal_core::Reader"><code>Reader</code></a> created by <a href="struct.Operator.html" title="struct opendal_core::Operator"><code>Operator</code></a> supports custom read control methods and can be converted |
| into [<code>futures::AsyncRead</code>] or [<code>futures::Stream</code>] for broader ecosystem compatibility.</p> |
