Module source 

Source front-end: turning tzdata text into a typed Database.

Pipeline within this module:

bytes --lexer::tokenize--> Vec<Line>  --parser::parse_into--> Database

• lexer handles field splitting, comments, quoting, and input-hardening limits.
• names resolves month/weekday/keyword abbreviations the way zic does.
• records holds the lexical Line/Field types.
• parser builds the typed Rule/Zone/Link records.

Modules

leap

Leap-source parsing (T11.2 — the grammar wall).

lexer

The lexer: bytes → Lines of Fields.

names

Case-insensitive, unambiguous-prefix matching for the English names zic recognises: month names, weekday names, and a handful of keywords (minimum, maximum, only).

parser

The parser: lexed Lines → a typed Database of Rule/Zone/Link records.

records

Lexical records: the output of the lexer, before any semantic interpretation.
