Module parser 

Zero-copy TSJSON line parser.

Parses TSJSON (tab-separated fields with JSON payload) event lines into Event structs or partially-parsed PartialEvent records. Designed for high-throughput scanning of event shard files.

TSJSON Format (v1, 8-field)

wall_ts_us \t agent \t itc \t parents \t type \t item_id \t data \t event_hash

• Comment lines start with # and are returned as ParsedLine::Comment.
• Blank/whitespace-only lines are returned as ParsedLine::Blank.
• Data lines are split on exactly 7 tab characters (yielding 8 fields).

Zero-copy

PartialEvent borrows &str slices from the input line wherever possible. Full parse (parse_line) copies into owned Event only after validation succeeds.

Structs

EventParser

Streaming event parser.

PartialEvent

A partially-parsed event that borrows from the input line.

Enums

ParseError

Errors that can occur while parsing a TSJSON line.

ParsedLine

The result of parsing a single line from a TSJSON shard file.

PartialParsedLine

The result of partially parsing a single line.

Constants

CURRENT_VERSION

The current event log format version understood by this build of bones.

FIELD_COMMENT

The field comment line that follows the shard header.

SHARD_HEADER

The shard header line written at the top of every .events file.

Functions

detect_version

Detect the event log format version from the first line of a shard file.

parse_line

Fully parse and validate a TSJSON line into a ParsedLine.

parse_line_partial

Parse a TSJSON line into a PartialParsedLine without deserializing the JSON payload or verifying the event hash.

parse_lines

Parse multiple TSJSON lines, skipping comments and blanks.
