Struct StreamState 

pub struct StreamState {
    pub chunks_received: u64,

    pub last_chunk_time_ms: u64,
    pub in_tool_call: bool,
    pub current_tool_id: Option<String>,

}

Stream state that can be preserved across reconnections

Fields

last_chunk_time_ms: u64

Last successful chunk timestamp (ms since stream start)

in_tool_call: bool

Whether the stream was in the middle of a tool call

current_tool_id: Option<String>

Current tool call ID if in progress

tool_args_buffer: String

Accumulated tool arguments if in progress
