Struct ProcessProgram 

pub struct ProcessProgram { /* private fields */ }

Executable, fixed arguments, and child environment for an isolated plugin. 隔离插件使用的程序、固定参数与子进程环境。

Implementations

impl ProcessProgram

pub fn new(executable: impl Into<PathBuf>) -> Self

Start a program specification with no fixed arguments. 以无固定参数开始描述一个程序。

pub fn argument(self, argument: impl Into<String>) -> Self

Append one fixed argument, passed before every operation name. 追加一个固定参数，它排在每个操作名之前。

pub fn environment( self, key: impl Into<String>, value: impl Into<String>, ) -> Self

Set one environment variable for the child. 为子进程设置一个环境变量。

This is the companion of ProcessLimits::inherit_env: with the environment cleared, these are the only variables the child sees, so a host passes what the plugin genuinely needs instead of handing over everything it has. 这是 ProcessLimits::inherit_env 的配套：清空环境后，子进程只看到这里设置的变量， 因此宿主传的是插件真正需要的东西，而不是把自己拥有的一切都交出去。

pub fn current_dir(self, directory: impl Into<PathBuf>) -> Self

Run the child in directory instead of the host’s working directory. 让子进程在 directory 中运行，而不是宿主的工作目录。

pub fn executable(&self) -> &Path

The configured executable path, before staging. 配置的可执行文件路径，尚未暂存。
