API usage

With client

The client library is implemented in the module diagramer::client.

```rust use diagramer::client::Client;

let client = Client::new(); let session = client.newsession("http://localhost:8000").await; println!("New session url {}", session.sessionurl()); session.addlink("a", "b", Some("Request")).await; session.addlink("b", "c", Some("Forward")).await; session.add_link("c", "a", Some("Response")).await; ```

The network based stress test also uses the client implementation.

Direct HTTP access

Create a new session

sh curl -XPOST 'http://127.0.0.1:8000/api/new-session'

With a session ID and a URI to the session

json { "id": "2888964795923373081", "uri": "/api/session/2888964795923373081" }

Add a link from a to b with label with a label

sh curl -XPOST -H 'Content-Type: application/json' 'http://127.0.0.1:8000/api/session/2888964795923373081/links' -d '{"from":"a", "to":"b", "label":"with a label"}'

Get a JSON representation of the session

sh curl 'http://127.0.0.1:8000/api/session/2888964795923373081'

json { "id": 2888964795923373000, "links": [ { "timestamp": 1676679312120, "from": "a", "to": "b", "label": "with a label", "id": 2 } ], "last_link": 2, "mermaid_url": "/api/session/2888964795923373081/mermaid", "svg_url": "/api/session/2888964795923373081/svg" }
