Enum TraceMode 

pub enum TraceMode {
    Off,
    ErrorsOnly,
    Full,
}

Runtime collection policy. 运行时追踪收集策略。

Off is the release-safe default for runtime traces. ErrorsOnly keeps evidence only for a failed result/panic scope, while Full retains every observed frame, local, and data edge. Off 是运行时追踪的发布安全默认值；ErrorsOnly 只保留 失败结果或 panic 作用域中的证据；Full 保留全部帧、局部值和数据边。

Variants

Off

Do not allocate or retain runtime evidence. 不分配也不保留运行时证据。

ErrorsOnly

Retain evidence only when an error scope fails. 只有错误作用域失败时才保留证据。

Full

Retain all observed runtime evidence. 保留全部观察到的运行时证据。
