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

컨트랙트

  1. assert JSONHandler writes time, level and msg in that order under slog's built-in key constants
  2. assert the JSON timestamp is RFC3339Nano with a variable-length fraction, while TextHandler and tint pad a time attribute to exactly three digits
  3. assert a zero Record.Time drops the timestamp field entirely
  4. assert ReplaceAttr renames the level and message keys and drops a field by returning a zero Attr
  5. assert a ReplaceAttr without a len(groups) guard renames a user attribute named msg inside a group as well
  6. assert the guard still cannot protect the built-in msg from a top-level attribute of the same name: the record carries two message keys and the JSON decoder keeps the last
  7. assert only a zero Attr drops a field, while an empty value or an empty key is still written out
  8. assert ReplaceAttr is called for the built-ins with no open groups and for a group's contents with the group path, never for the group attr itself
  9. assert WithGroup nests later attributes, an empty group is omitted, and WithGroup with an empty name is a no-op
  10. assert JSONHandler ignores fmt.Stringer and json-marshals the struct, while LogValue wins on both handlers
  11. assert Handler.Enabled is consulted and Handle is skipped when the level is disabled
  12. assert LogValue does not run for a disabled level but plain call arguments are evaluated anyway, and only an explicit Enabled guard skips them
  13. assert a LogValuer passed to With is resolved once, at With time, and not again per record
  14. assert WithAttrs and WithGroup each return a new handler, so a child logger's attrs and open group reach neither the parent nor a sibling
  15. assert tint follows the same ReplaceAttr, group and LogValuer contract but formats a Stringer with %+v and writes ANSI escapes to a non-terminal unless NoColor is set
  16. assert tint.NewHandler is the constructor deprecated in v1.2.0 and produces output identical to tint.NewTextHandler
