pub struct Context { /* private fields */ }

Implementations

impl Context

pub fn new(messages: Vec<ChatMessage>, tools: Vec<ToolDefinition>) -> Self

pub fn prompt_cache_key(&self) -> Option<&str>

pub fn set_prompt_cache_key(&mut self, key: Option<String>)

pub fn reasoning_effort(&self) -> Option<ReasoningEffort>

pub fn set_reasoning_effort(&mut self, effort: Option<ReasoningEffort>)

pub fn add_message(&mut self, message: ChatMessage)

pub fn set_tools(&mut self, tools: Vec<ToolDefinition>)

pub fn messages(&self) -> &Vec<ChatMessage>

pub fn tools(&self) -> &Vec<ToolDefinition>

pub fn message_count(&self) -> usize

Returns the number of messages in the context

pub fn estimated_token_count(&self) -> u32

Estimate total token count using the ~4 bytes/token heuristic. Includes messages and tool definitions. Used for pre-flight overflow detection.

pub fn push_assistant_turn( &mut self, content: &str, reasoning: AssistantReasoning, completed_tools: Vec<Result<ToolCallResult, ToolCallError>>, )

Build an assistant turn and its tool call results and append them to messages.

pub fn filter_encrypted_reasoning(&self, model: &LlmModel) -> Self

Return a copy with encrypted reasoning filtered for the given model. Encrypted content is kept only when its source model matches.

pub fn clear_conversation(&mut self)

Clear all non-system messages, retaining only system prompts.

pub fn messages_for_summary(&self) -> Vec<&ChatMessage>

Get all non-system messages for summarization

pub fn with_compacted_summary(&self, summary: &str) -> Context

Create a new context with all messages replaced by a summary. Preserves the system prompt and tools.

where __S: Serializer,

Serialize this value into the given Serde serializer.
