Struct ClaudeCodeLog 

pub struct ClaudeCodeLog {
    pub cwd: String,
    pub session_id: String,
    pub log_type: String,
    pub timestamp: String,
    pub message: Option<ClaudeMessage>,
    pub tool_use_result: Option<ClaudeToolUseResult>,
    pub is_sidechain: bool,
}

Single log entry from a Claude Code session file.

Only fields the analyzer actually reads are materialised. Large unrelated payloads — assistant text content, tool_result bodies, parentUuid, version metadata — are dropped by serde during parse so they never retain memory, which is what keeps long sessions from ballooning the working set.

Fields

cwd: String

Working directory the session ran in.

session_id: String

Session identifier.

log_type: String

Record type discriminator (e.g. user, assistant).

timestamp: String

ISO-8601 timestamp string for the record.

message: Option<ClaudeMessage>

The message body, when the record carries one.

tool_use_result: Option<ClaudeToolUseResult>

Legacy top-level toolUseResult; absent on subagent records.

is_sidechain: bool

true for records inside a subagent JSONL (<session>/subagents/agent-*.jsonl). Subagent records do not carry the top-level toolUseResult field, so the analyzer falls back to scanning message.content[].tool_result for them. Main-session records (isSidechain == false or missing) skip the fallback to avoid double-counting tool results that already arrived via toolUseResult.
