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.

MIGRATION- 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
- 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
- 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
- assert alt takes the first matching branch rather than the longest, so reordering the same two branches changes which one wins
- 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
- assert dec_uint stops at a leading zero, yielding 0 and leaving the remaining digits, while digit1 with parse_to accepts zero padding
- 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
- assert the built-in expression Pratt parser honours binding power, left and right associativity, and an operator that returns an error
