Files

• mod.rs - HttpFaasExecutor struct implementing FaasExecutor. Supports a base URL with optional per-job endpoint overrides. Invokes via HTTP POST, health-checks via GET to the job endpoint. deploy_job and undeploy_job are no-ops (returns Ok) since deployment is managed externally.

Key APIs

• HttpFaasExecutor::new(base_url) - constructor with base URL for function invocations
• HttpFaasExecutor::with_job_endpoint(job_id, url) - register a custom endpoint for a specific job
• FaasExecutor::invoke(job_id, input) - POST JSON payload to the job's endpoint
• FaasExecutor::health_check(job_id) - GET request to verify endpoint availability
• FaasExecutor::deploy_job / undeploy_job - no-op implementations

Relationships

• Implements FaasExecutor trait defined in the parent blueprint-faas crate
• Designed for self-hosted or non-standard serverless platforms (OpenFaaS, Knative, custom HTTP services)
• Peer to aws/, azure/, gcp/, and digitalocean/ executor implementations
