greentic-distributor-client

Client trait and HTTP/WIT implementations for the greentic:distributor-api@1.0.0 world. Provides:

• DistributorClient async trait for resolving components, querying pack status, and warming packs.
• HttpDistributorClient for JSON/HTTP endpoints.
• WitDistributorClient adapter that translates DTOs to greentic-interfaces-guest distributor-api bindings; use GeneratedDistributorApiBindings on WASM targets to call the distributor imports.

Uses DTOs from greentic-types and supports optional auth headers and request timeouts.

Usage

use greentic_distributor_client::{
    DistributorClient, DistributorClientConfig, DistributorEnvironmentId, EnvId, HttpDistributorClient,
    ResolveComponentRequest, TenantCtx, TenantId,
};
use serde_json::json;

let config = DistributorClientConfig {
    base_url: Some("https://distributor.example.com".into()),
    environment_id: DistributorEnvironmentId::from("env-1"),
    tenant: TenantCtx::new(EnvId::try_from("prod").unwrap(), TenantId::try_from("tenant-a").unwrap()),
    auth_token: None,
    extra_headers: None,
    request_timeout: None,
};

let client = HttpDistributorClient::new(config)?;
let resp = client.resolve_component(ResolveComponentRequest {
    tenant: TenantCtx::new(
        EnvId::try_from("prod").unwrap(),
        TenantId::try_from("tenant-a").unwrap(),
    ),
    environment_id: DistributorEnvironmentId::from("env-1"),
    pack_id: "pack-123".into(),
    component_id: "component-x".into(),
    version: "1.0.0".into(),
    extra: json!({}),
}).await?;
println!("artifact: {:?}", resp.artifact);

For WIT, implement DistributorApiBindings using the generated greentic_interfaces_guest::distributor_api functions and pass it to WitDistributorClient. GeneratedDistributorApiBindings is provided for WASM targets. On non-WASM targets it returns an error; prefer HttpDistributorClient there.

Local dev distributor

Use the companion greentic-distributor-dev crate to serve packs/components from a local directory, useful for greentic-dev and conformance tests:

use greentic_distributor_client::{ChainedDistributorSource, DistributorSource, PackId, Version};
use greentic_distributor_dev::{DevConfig, DevDistributorSource};

let dev_source = DevDistributorSource::new(DevConfig::default());
let sources = ChainedDistributorSource::new(vec![Box::new(dev_source)]);

let pack_bytes = sources.fetch_pack(&PackId::try_from("dev.local.hello-flow")?, &Version::parse("0.1.0")?);
println!("Loaded {} bytes", pack_bytes.len());
