Enum ChatEvent 

pub enum ChatEvent {
    UserText {
        timestamp_ms: u64,
        text: String,
    },
    AssistantText {
        timestamp_ms: u64,
        message_id: String,
        model: String,
        text: String,
    },
    Thinking {
        timestamp_ms: u64,
        message_id: String,
        model: String,
        text: String,
    },
    ToolUse {
        timestamp_ms: u64,
        message_id: String,
        tool_use_id: String,
        name: String,
        input_json: String,
    },
    ToolResult {
        timestamp_ms: u64,
        tool_use_id: String,
        content: String,
        is_error: bool,
    },
}

Flat, timestamp-ordered event stream extracted from a Claude Code session’s JSONL. Produced by parse_chat_events and rendered by the frontend chat view. This is a read-only projection of the same file used by the usage tracker — the live PTY remains the input path.

Pairing of ToolUse → ToolResult is left to the frontend via tool_use_id so the event stream stays flat and cheap to serialize.

Variants

UserText

A real user turn (keyboard input). Does NOT include tool_result entries — those are emitted as ToolResult below.

Fields

timestamp_ms: u64

text: String

AssistantText

Assistant text block. One ChatEvent::AssistantText per text block in the assistant message; turns with no text block emit none.

Fields

timestamp_ms: u64

message_id: String

model: String

text: String

Thinking

Extended-thinking block (Opus). Collapsed by default in the UI.

Fields

timestamp_ms: u64

message_id: String

model: String

text: String

ToolUse

Tool invocation by the assistant. input_json is the raw JSON of the input field, serialized as a string — the frontend decides whether to pretty-print, truncate, or tree-render.

Fields

timestamp_ms: u64

message_id: String

tool_use_id: String

name: String

input_json: String

ToolResult

Tool result injected by the harness. Pairs with a ToolUse by tool_use_id. content is the text payload (stringified if the JSONL stored it as a block array).

Fields

timestamp_ms: u64

tool_use_id: String

content: String

is_error: bool
