Struct ProviderCapabilities

}

Declared capabilities of one provider-model pair (spec §20.3).

Fields

structured_output: StructuredOutputCapability

Structured-output transport.

tool_calling: ToolCallingCapability

Tool-calling support.

parallel_tool_calls: bool

Whether several tool calls may appear in one response.

vision: bool

Image input.

documents: bool

Document input — a PDF, a spreadsheet, a plain-text attachment.

Separate from vision on purpose: a model that reads a PNG may reject a PDF, and a gateway may strip one and not the other. Defaults to false when a stored declaration predates the flag, which is the fail-closed answer.

audio_input: bool

Audio input.

audio_output: bool

Audio output.

streaming: bool

Incremental output.

prompt_caching: bool

Prompt caching honoured by the provider.

reasoning_controls: bool

Reasoning effort or budget controls.

temperature: bool

Whether a sampling temperature may be sent. Reasoning models that accept only their default declare false, and the adapter then drops the parameter.

seed: bool

Whether a sampling seed is honoured.

max_context_tokens: Option<u64>

Context window in tokens, when known.

preserves_call_ids: bool

Whether tool-call ids round-trip unchanged.

Implementations

impl ProviderCapabilities

pub const fn minimal() -> Self

The weakest declaration: nothing supported, context unknown.

pub const fn with_structured_output( self, capability: StructuredOutputCapability, ) -> Self

Sets the structured-output transport.

pub const fn with_tool_calling(self, capability: ToolCallingCapability) -> Self

Sets tool calling; Parallel also sets parallel_tool_calls.

pub const fn with_streaming(self, streaming: bool) -> Self

Sets streaming support.

pub const fn with_vision(self, vision: bool) -> Self

Sets vision support.

pub const fn with_documents(self, documents: bool) -> Self

Sets document-input support.

pub const fn with_max_context_tokens(self, tokens: u64) -> Self

Sets the context window.

pub const fn with_preserves_call_ids(self, preserves: bool) -> Self

Sets whether call ids round-trip.

pub const fn with_prompt_caching(self, caching: bool) -> Self

Sets prompt caching support.

pub const fn with_reasoning_controls(self, controls: bool) -> Self

Sets whether reasoning effort may be sent.

pub const fn with_temperature(self, temperature: bool) -> Self

Sets whether a sampling temperature may be sent.

pub const fn with_seed(self, seed: bool) -> Self

Sets whether a sampling seed is honoured.

pub const fn supports_tools(&self) -> bool

Returns true when any tool calling is available.

Trait Implementations

impl Clone for ProviderCapabilities

fn clone(&self) -> Self
