Struct LlmCallConfigBuilder 

pub struct LlmCallConfigBuilder { /* private fields */ }

Builder for LlmCallConfig with fluent API

Chain methods like reasoning_effort(), temperature(), etc. and call build() to get the final config. To start from a core RuntimeAgent, use everruns_core::llm_conversions::llm_call_config_builder_from_agent.

Implementations

impl LlmCallConfigBuilder

pub fn from_config(config: LlmCallConfig) -> LlmCallConfigBuilder

Construct a builder wrapping an existing config.

pub fn reasoning_effort(self, effort: impl Into<String>) -> LlmCallConfigBuilder

Set reasoning effort level (for models that support it: low, medium, high)

pub fn speed(self, speed: impl Into<String>) -> LlmCallConfigBuilder

Set speed (service tier): “flex”, “default”, or “priority”

pub fn verbosity(self, verbosity: impl Into<String>) -> LlmCallConfigBuilder

Set verbosity: “low”, “medium”, or “high”

pub fn model(self, model: impl Into<String>) -> LlmCallConfigBuilder

Set the model

pub fn temperature(self, temp: f32) -> LlmCallConfigBuilder

Set temperature

pub fn max_tokens(self, tokens: u32) -> LlmCallConfigBuilder

Set max tokens

pub fn tools(self, tools: Vec<ToolDefinition>) -> LlmCallConfigBuilder

Set tools

pub fn metadata(self, metadata: HashMap<String, String>) -> LlmCallConfigBuilder

Set metadata for API tracking

This metadata is sent to the LLM provider for tracking and debugging. Typically includes session_id, agent_id, org_id, turn_id, exec_id.

pub fn with_metadata( self, key: impl Into<String>, value: impl Into<String>, ) -> LlmCallConfigBuilder

Add a single metadata key-value pair

pub fn previous_response_id(self, id: Option<String>) -> LlmCallConfigBuilder

Set previous response ID for stateful continuation

pub fn provider_opaque_context( self, context: Option<ProviderOpaqueContext>, ) -> LlmCallConfigBuilder

Set standalone provider-owned compact context for the request.

pub fn tool_search(self, config: ToolSearchConfig) -> LlmCallConfigBuilder

Set tool_search configuration

pub fn prompt_cache(self, config: PromptCacheConfig) -> LlmCallConfigBuilder

Set prompt caching configuration

pub fn openrouter_routing( self, config: OpenRouterRoutingConfig, ) -> LlmCallConfigBuilder

Set OpenRouter model fallback and provider routing controls.

pub fn parallel_tool_calls( self, parallel_tool_calls: Option<bool>, ) -> LlmCallConfigBuilder

Set the request-level parallel tool calling preference (EVE-598).

pub fn volatile_suffix_len(self, len: usize) -> LlmCallConfigBuilder

Set the number of trailing volatile messages that must not anchor a message-level prompt-cache breakpoint (see LlmCallConfig::volatile_suffix_len).

pub fn build(self) -> LlmCallConfig

Build the configuration
