Available on (crate features test-utils) and not (target_os=unknown and WebAssembly) only.

Per-provider wire frames for the shared scenario set.

Option fields cover sequence shapes a wire family cannot spell (e.g. ollama’s NDJSON has no event types, so no “unknown event type” frame).

Fields

driver: WireDriver

The provider’s full pipeline.

text_frames: Vec<WireInput>

Frames that deliver exactly the text deltas in expected_texts.

expected_texts: Vec<&'static str>

The text deltas text_frames delivers, in order.

tool_call_frames: Vec<WireInput>

Frames that fully deliver one tool call (including any completion signal the wire needs, but no stream terminal).

expected_tool_name: &'static str

Name of the tool call tool_call_frames delivers.

partial_tool_call_frames: Option<Vec<WireInput>>

Frames that leave a tool call mid-arguments, where the wire streams arguments incrementally.

terminal_frames: Vec<WireInput>

The provider’s genuine stream terminal, carrying usage.

expected_usage_total: u64

Total tokens terminal_frames reports.

expected_finish_reason: Option<FinishReason>

Finish reason terminal_frames reports.

zero_usage_terminal_frames: Option<Vec<WireInput>>

A genuine terminal that reports no usage metrics at all.

bare_terminal_frames: Option<Vec<WireInput>>

A terminal signal that carries no data of its own (e.g. a bare [DONE]), for wires that have one.

malformed_frame: Option<WireInput>

A frame that fails the wire decode entirely. None only for typed-event wires, whose SDK surfaces decode failures as transport errors — a frame-level corrupt input cannot be spelled there.

unknown_event_frame: Option<WireInput>

An event type this client does not know, for typed-event wires.

defective_known_frame: Option<WireInput>

A known event whose payload is schema-defective.

delta_less_prelude_frame: Option<WireInput>

A delta-less choice prelude (the Azure prompt_filter_results shape).

refusal: Option<RefusalFixture>

Refusal content frames, where the wire has a refusal channel.

interleaved_reasoning: Option<InterleavedReasoningFixture>

The interleaving-boundary shape, where the wire’s reasoning identity is a constant per-stream minted key (its adapter synthesizes the reasoning ends other output implies).

Implementations

impl ProviderWireFixture

pub fn capabilities(&self) -> SuiteCapabilities

The capability set this fixture’s populated optional fields spell — the descriptor the suite macro gates scenarios on.

Deriving flags here (instead of hand-writing them per suite invocation) makes flag/fixture drift structurally impossible: a shape the fixture supplies is a declared capability, a shape it lacks is a visible named skip, and there is nothing else to keep in sync.
