TreeDX Rust SDK

treedx is the generic Rust SDK for TreeDX. The library crate is treedx. It implements the shared packages/sdk-spec architecture, follows docs/api/openapi.yaml, and does not encode TreeSeed product semantics. packages/trsd-sdk is a downstream TreeSeed consumer/reference only.

The current sdk-manifest.yaml reports modules, capabilities, and test roots as implemented. The SDK exposes all 113 /api/v1 OpenAPI operations through first-class module methods and a validated raw operation fallback.

Install

Add the crate:

cargo add treedx

Use the library crate:

use treedx::{TreeDxClient, TreeDxConfig, TreeDxApiError};

Configure Client

use treedx::{TreeDxClient, TreeDxConfig};

let client = TreeDxClient::new(TreeDxConfig {
    base_url: "http://localhost:4000".to_string(),
    token: Some("token".to_string()),
    ..Default::default()
});

The client also supports custom auth providers and injected transports for tests or embedding.

Authenticate

Bearer authentication uses the Authorization: Bearer <token> header. Tokens may come from TreeDxConfig.token or an auth provider. The SDK must not place production identity in request JSON and must not log bearer tokens.

Basic Health Call

# async fn example(client: treedx::TreeDxClient) -> treedx::TreeDxResult<()> {
let health = client.health().await?;
let version = client.version().await?;
# Ok(())
# }

Repository Query

Repository-scoped query helpers live under client.query():

# async fn example(client: treedx::TreeDxClient) -> treedx::TreeDxResult<()> {
let results = client
    .query()
    .search_files("repo_demo", serde_json::json!({
        "query": "release provenance",
        "paths": ["docs/**"]
    }))
    .await?;

let file = client
    .query()
    .read_file("repo_demo", serde_json::json!({
        "ref": "refs/heads/main",
        "path": "docs/index.md"
    }))
    .await?;
# Ok(())
# }

Workspace File Lifecycle

Workspace-scoped file helpers live under client.workspaces() and client.files():

# async fn example(client: treedx::TreeDxClient) -> treedx::TreeDxResult<()> {
let workspace = client
    .workspaces()
    .create("repo_demo", serde_json::json!({ "ref": "refs/heads/main" }))
    .await?;

client
    .files()
    .write("workspace_123", serde_json::json!({
        "path": "docs/new.md",
        "content": "# New"
    }))
    .await?;

client
    .files()
    .patch("workspace_123", serde_json::json!({
        "path": "docs/new.md",
        "patch": "..."
    }))
    .await?;

client
    .files()
    .commit("workspace_123", serde_json::json!({ "message": "Update docs" }))
    .await?;

client.workspaces().close("workspace_123", serde_json::json!({})).await?;
# Ok(())
# }

Blob Upload And Download

Binary helpers use bytes::Bytes and do not expose string constructors for binary upload bodies.

# async fn example(client: treedx::TreeDxClient) -> treedx::TreeDxResult<()> {
client
    .blobs()
    .upload("workspace_123", bytes::Bytes::from_static(&[1, 2, 3]), None)
    .await?;

let blob = client.blobs().download("workspace_123", None).await?;
# Ok(())
# }

Multipart helpers expose create, part upload, complete, and abort.

Graph And Context Query

# async fn example(client: treedx::TreeDxClient) -> treedx::TreeDxResult<()> {
client.graph().refresh("repo_demo", serde_json::json!({})).await?;
let graph = client.graph().query("repo_demo", serde_json::json!({ "query": "MATCH ..." })).await?;
let context = client.context().build("repo_demo", serde_json::json!({ "query": "ctx docs" })).await?;
let parsed = client.context().parse("repo_demo", serde_json::json!({ "source": "ctx docs" })).await?;
# Ok(())
# }

Federated Query

Federation helpers use portfolio/global TreeDX routes rather than a single configured repository:

# async fn example(client: treedx::TreeDxClient) -> treedx::TreeDxResult<()> {
let plan = client.federation().plan(serde_json::json!({ "query": "release provenance" })).await?;
let results = client.federation().search(serde_json::json!({ "query": "release provenance" })).await?;
# Ok(())
# }

Scoped Admin And Internal Modules

Full OpenAPI coverage includes sensitive scoped modules: Admin, Audit, Policy, SearchIndex, and FederationInternal. These APIs require appropriate TreeDX credentials and should be used carefully against production systems. They remain generic TreeDX APIs and do not encode TreeSeed product semantics.

The raw operation fallback validates method/path pairs against generated OpenAPI metadata before dispatch.

Error Handling

Errors are exposed as TreeDxApiError with status, code, message, details, and payload. Network failures use status=0 and code="network_error".

Pagination

TreeDxPage and TreeDxCursor preserve opaque server-owned cursor values and nextCursor/hasMore metadata.

Binary And Multipart

Binary payloads use bytes::Bytes. Multipart part numbers are passed through to TreeDX without SDK renumbering.

Conformance

The crate loads Phase 7 black-box scenario records and reports NotConfigured until live scenario dispatch is implemented. It must not fake conformance success.

cargo test

Integration

Integration tests call a live TreeDX server only when TREEDX_BASE_URL is set. Without that environment variable, they pass cleanly by reporting not-configured behavior.
