Enum SystemError 

#[non_exhaustive]
pub enum SystemError {
    None,
    Timeout(Duration),
    CompileFailed,
    CargoFailed,
    ProcessSpawnFailed(String),
}

Available on crate feature dyntest only.

动态测试运行的系统级错误（区别于被测程序自身的失败）。

未来可能新增变体，请勿依赖穷尽匹配（匹配时请保留通配分支）。

Feature Requirement

需要同时启用 "dyntest" 与 "std" 特性。

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

None

无系统级错误；ok == false 时表示被测程序自身返回非零退出码。

Timeout(Duration)

执行超时并已被终止，载荷为超时阈值。

CompileFailed

cargo build 失败（退出码非零）。

CargoFailed

DnyRun::cargo 执行的自定义 cargo <args> 命令返回非零退出码（超时、启动失败除外，分别记为 Timeout / ProcessSpawnFailed）。

ProcessSpawnFailed(String)

子进程无法启动，载荷为系统错误描述。
