Crate sim_lib_agent_runner_core 

Provider-neutral runner contracts for SIM model fabrics.

This crate defines the shared in-process objects used by SIM model runners:

• ModelRequest for normalized task and transcript input
• ModelResponse for final content and usage output
• ModelEvent and ModelEventSink for streaming progress
• ModelCard and ModelBid for routing and selection
• ModelRunner for executable runner implementations

Higher-level crates install concrete runners, policies, markets, and agent-model adapters on top of these contracts.

Structs

InjectionFence

Deterministic model-input fence tied to immutable content.

ModelBid

One availability/score proposal produced for market-style runner selection.

ModelCard

Metadata describing one runner/model candidate for routing and inspection.

ModelEvent

Structured streaming event emitted by a model runner.

ModelRequest

Normalized model request used across providers and local runners.

ModelResponse

Final response returned by a runner after inference completes.

ModelUsage

Usage and accounting information attached to a model response.

OutputContract

Output obligations attached to a model request.

VecEventSink

In-memory event sink used by tests and buffered callers.

Constants

FENCE_DATA_RULE

Instruction every consumer emits next to fenced data.

OUTPUT_GRAMMAR_EXTRA

Model-request extension key for a best-effort output grammar.

OUTPUT_GRAMMAR_REQUIRED_EXTRA

Model-request extension key marking whether the grammar is required.

RETURN_CODEC_EXTRA

Model-request extension key for the required return codec.

RETURN_SHAPE_EXTRA

Model-request extension key for the normalized return shape expression.

Statics

RECIPES

Cookbook recipes embedded from this crate’s recipes/ directory.

Traits

ModelEventSink

Sink for streaming model events emitted during inference.

ModelRunner

Executable contract for a model backend or model-like runtime surface.
