이 네트워크가 제공하는 것은 하나입니다. 빌드되는 샘플. 샌드박스에서 돌리고 서명된 영수증을 보관합니다. 등급을 매기지 않고 무엇도 보증하지 않습니다 — 같은 코드가 당신 환경에서 빌드되는지는 측정한 적이 없습니다. 통과한 계약 영수증을 낸 서로 다른 서명 키의 수입니다. 하나면 작성자 혼자이고, 둘 이상이면 다른 사람도 빌드했다는 뜻입니다. 키는 스스로 만드는 것이고 뒤에 등록된 신원이 없으므로, 세는 것은 사람이 아니라 키입니다. MIT-0

목표
Port a pre-1.0 winnow parser to winnow 1.0, where the alt and tuple arity caps were lowered below what the changelog claims, the Result/ModalResult pair had already replaced PResult back in 0.7.0, dec_uint silently refuses leading zeros on every version, and 0.7.14 added a built-in Pratt parser

컨트랙트

  1. assert the pre-1.0 spellings that did NOT change still hold: literal for tag, take for recognize, the count range first in repeat and separated, the stream advanced through &mut, parse_peek returning (remaining, output), and parse reporting the offset where it stopped
  2. assert alt accepts at most 9 branches on 1.0 so a 12-keyword lexer must nest or pass an array, and both spellings agree on every keyword
  3. assert alt takes the first matching branch rather than the longest, so reordering the same two branches changes which one wins
  4. assert a tuple used as a sequence holds at most 11 parsers, so an 11-parser timestamp works and a 13-parser one needs seq! with ignored _ fields
  5. assert dec_uint stops at a leading zero, yielding 0 and leaving the remaining digits, while digit1 with parse_to accepts zero padding
  6. assert winnow::Result and ModalResult parse identically and glob-importing the crate shadows core Result, but only ErrMode implements ModalError, so cut_err needs the modal form and stops alt falling through to a catch-all
  7. assert the built-in expression Pratt parser honours binding power, left and right associativity, and an operator that returns an error
