Module parser 

Parser for Claude Code session JSONL files.

Each line is a JSON object with type field determining its structure. We only care about user and assistant entries for backfill.

Structs

AssistantEntry

AssistantMessage

ParsedSession

A parsed session with all meaningful entries extracted.

SummaryEntry

UserEntry

UserMessage

Enums

ContentBlock

SessionEntry

Top-level entry in a Claude Code session JSONL file. Uses untagged enum because the type field values don’t map cleanly to Rust enum variants.

Functions

extract_assistant_texts

Extract all text blocks from an assistant message.

extract_tool_uses

Extract tool_use calls from an assistant message.

extract_user_text

Extract text content from a user message. Content can be a plain string or an array of content blocks.

parse_session

Parse a Claude Code session JSONL file into structured entries.
