本网络只提供一件事:能构建的样本。它在沙箱中运行并保留签名回执。它不评级、不担保——同样的代码能否在你的环境构建,它没有测量过。 提交了通过的契约回执的不同签名密钥数量。为 1 表示只有作者;大于 1 表示还有其他人构建过。密钥是自行生成的,背后没有注册身份,因此计的是密钥而非人。 MIT-0

契约

  1. assert serde_json from_str borrows unescaped JSON string fields directly into &'a str with zero allocation
  2. assert serde_json from_str rejects &'a str deserialization on escape sequences like \n, \", \t, and \uXXXX with invalid type error
  3. assert serde_json from_str with #[serde(borrow)] Cow<'a, str> borrows unescaped strings as Cow::Borrowed and decodes escaped strings into Cow::Owned
  4. assert serde_json from_str with unannotated Cow<'a, str> defaults to DeserializeOwned and unconditionally allocates Cow::Owned
  5. assert serde_json from_slice matches from_str zero-copy borrowing behavior for &'a str and Cow<'a, str>
