Migrate Rust examples to SDK 0.11.0 service API#407
Merged
Conversation
The Rust SDK 0.11.0 replaces the trait-based service definition with a struct-based one: the macro (#[service]/#[object]/#[workflow]) goes on the struct's impl block, each handler is annotated with #[handler], and shared/exclusive is inferred from the context type. Services are bound with .bind(Struct) instead of .bind(StructImpl.serve()). Updates all examples in rust/basics and both rust/templates. Service and handler names are preserved, so HTTP endpoints and generated clients (e.g. SubscriptionServiceClient) are unchanged. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

What
Rust SDK 0.11.0 changes how services are defined. The old trait-based definition is deprecated in favor of a struct-based one:
#[service]/#[object]/#[workflow]macro now goes on the struct'simplblock (no separate trait).#[handler].ObjectContextvsSharedObjectContext,WorkflowContextvsSharedWorkflowContext) — no more#[shared]..bind(Struct)instead of.bind(StructImpl.serve()).Changes
Migrated every Rust example to the new API:
rust/basics—p0_durable_execution,p1_building_blocks,p2_virtual_objects,p3_workflows, andstubsrust/templates/rustrust/templates/rust-shuttleService and handler names are preserved, so HTTP endpoints and generated clients (e.g.
SubscriptionServiceClient) are unchanged.Verification
