Struct HarmonyContext 

pub struct HarmonyContext { /* private fields */ }

Context for tracking Harmony parsing state within a sequence.

This wraps the openai-harmony crate’s StreamableParser and provides delta extraction for streaming responses.

Implementations

impl HarmonyContext

pub fn new() -> Result<Self, Error>

Create a new Harmony parsing context

pub fn process_token(&mut self, token_id: u32) -> HarmonyDelta

Process a token and return any new delta content

pub fn current_channel(&self) -> Option<HarmonyChannel>

Get the currently active channel

pub fn accumulated(&self) -> &HarmonyAccumulated

Get all accumulated content

pub fn reasoning_content(&self) -> Option<String>

Get accumulated reasoning content (analysis + commentary)

pub fn final_content(&self) -> Option<String>

Get accumulated final content

pub fn get_reasoning_delta(&mut self) -> Option<String>

Get the reasoning delta since last call (for streaming). Returns new reasoning content that hasn’t been sent yet.

pub fn get_final_delta(&mut self) -> Option<String>

Get the final content delta since last call (for streaming). Returns new final content that hasn’t been sent yet.

pub fn process_eos(&mut self)

Signal end of stream to the parser

pub fn current_recipient(&self) -> Option<String>

Get the recipient (for tool calls) if any

pub fn has_tool_call(&self) -> bool

Check if there’s a tool call in progress

pub fn get_tool_calls(&self) -> &[HarmonyToolCall]

Get all completed tool calls

pub fn get_current_tool_call(&self) -> Option<(&str, &str)>

Get the current tool call being built (if any) Returns (recipient, arguments_so_far)

pub fn finalize_tool_calls(&mut self) -> Vec<HarmonyToolCall>

Finalize any pending tool call and return all tool calls. This should be called when the sequence is done. Note: This takes ownership of the tool calls, so calling it twice will return an empty vector the second time.
