Enum HeadlessStreamEvent 

pub enum HeadlessStreamEvent {
    TextDelta(String),
    ToolCall(ObservedToolCall),
    Done(HeadlessToolResponse),
}

Event emitted by HeadlessTurnProvider::converse_stream as the turn progresses.

Unlike StreamChunk (which only carries text deltas), this enum surfaces tool-call observations alongside text — keeping the rich metadata that HeadlessTurnProvider::converse returns at the end of the turn while delivering it incrementally.

Variants

TextDelta(String)

Partial assistant text — the next chunk to append to the in-flight assistant message.

ToolCall(ObservedToolCall)

A tool call was observed (start or status update). Each event is a snapshot of the tool call’s latest known state, so a consumer can either accumulate updates or replace by id.

Done(HeadlessToolResponse)

The turn has finished. Carries the aggregated HeadlessToolResponse — same shape that HeadlessTurnProvider::converse would have returned. Always emitted as the last event before the stream closes successfully.
