Stable native plugin ABI and Rust authoring helpers for NeMo Relay.

This crate intentionally does not depend on the nemo-relay runtime crate. Native plugins built with it communicate with a host through versioned C-compatible tables and host-owned string handles.

Macros

• nemo_relay_plugin: Exports a concrete plugin constructor as a native plugin entry symbol body.

Structs

• AnnotatedLlmRequest: Structured view of an LLM request, produced by a Codec from opaque LlmRequest content.
• AnnotatedLlmResponse: Structured view of an LLM response, produced by a response codec from raw JSON API output.
• CategoryProfile: Category-specific profile data.
• ConfigDiagnostic: Structured validation diagnostic for plugin validation.
• EventCategory: Semantic category carried by ATOF category.
• LlmAttributes: Bitflags that modify LLM-call behavior and observability.
• LlmNext: Typed continuation passed to LLM execution intercepts.
• LlmRequest: JSON-shaped LLM request payload passed through the runtime.
• LlmRequestInterceptOutcome: Result of an LLM request intercept that can schedule lifecycle marks.
• LlmStream: Host- or plugin-owned stream returned across the native LLM stream ABI.
• LlmStreamNext: Typed continuation passed to LLM stream execution intercepts.
• NemoRelayNativeHostApiV1: Versioned host API table passed to native plugin entry symbols.
• NemoRelayNativeLlmStreamV1: Native LLM JSON stream handle table.
• NemoRelayNativePluginContext: Opaque plugin registration context borrowed from the host during registration.
• NemoRelayNativePluginV1: Versioned plugin descriptor returned by native plugin entry symbols.
• NemoRelayNativeScopeHandle: Opaque host-owned scope handle.
• NemoRelayNativeScopeStack: Opaque host-owned scope stack handle.
• NemoRelayNativeScopeStackBinding: Opaque host-owned captured scope-stack binding.
• NemoRelayNativeString: Opaque host-owned UTF-8 string or JSON byte buffer.
• PendingMarkSpec: Mark requested by middleware for materialization by a lifecycle owner.
• PluginContext: Borrowed safe wrapper around a host plugin registration context.
• PluginRuntime: Cloneable high-level runtime handle for host APIs available to native plugins.
• ScopeAttributes: Bitflags that modify scope behavior and observability.
• ScopeGuard: RAII guard for a host scope opened by PluginRuntime::scope.
• ScopeHandle: Host-owned scope handle returned by native scope APIs.
• ScopeStack: Host-owned isolated scope stack returned by native scope-stack APIs.
• ScopeStackBinding: Captured thread-local scope-stack binding.
• ThreadScopeStackGuard: RAII guard that restores the previous thread-local scope stack on drop.
• ToolAttributes: Bitflags that modify tool-call behavior and observability.
• ToolExecutionInterceptOutcome: Canonical result returned by a tool execution intercept.
• ToolNext: Typed continuation passed to tool execution intercepts.

Enums

• DiagnosticLevel: Diagnostic severity returned by plugin validation.
• Event: Tagged union covering the two ATOF event kinds emitted by the runtime.
• HandleAttributes: Attribute bitflags attached to a concrete handle kind.
• NemoRelayNativeScopeType: Scope category used by native plugins when opening scopes.
• NemoRelayStatus: Status codes returned by stable native ABI functions.
• ScopeCategory: Agent Trajectory Observability Format (ATOF) lifecycle phase for a scope event.
• ScopeType: Semantic category attached to a scope lifecycle span.

Constants

• NEMO_RELAY_NATIVE_ABI_VERSION: Native plugin ABI version supported by this crate.

Traits

• NativePlugin: Trait implemented by Rust native plugins.

Functions

• NemoRelayNativeWithScopeStackCb: Native callback executed while a host scope stack is temporarily active.
• Result: Result type used by the Rust native plugin SDK.
