Struct subprocess::PopenConfig

pub struct PopenConfig {
    pub stdin: Redirection,
    pub stdout: Redirection,
    pub stderr: Redirection,
    pub detached: bool,
    pub executable: Option<OsString>,
    // some fields omitted
}

Options for Popen::create.

When constructing PopenConfig, always use the Default trait, such as:

Popen::create(argv, PopenConfig {
     stdout: Redirection::Pipe,
     detached: true,
     // ... other fields you want to override ...
     ..Default::default()
})

This ensures that fields added later do not break existing code.

An alternative to using PopenConfig directly is creating processes using Exec, a builder for Popen.

Fields

stdin: Redirection

How to configure the executed program's standard input.

stdout: Redirection

How to configure the executed program's standard output.

stderr: Redirection

How to configure the executed program's standard error.

detached: bool

Whether the Popen instance is initially detached.

executable: Option<OsString>

Executable to run.

If provided, this executable will be used to run the program instead of argv[0]. However, argv[0] will still be passed to the subprocess, which will see that as argv[0]. On some Unix systems, ps will show the string passed as argv[0], even though executable is actually running.

Methods

impl PopenConfig

fn try_clone(&self) -> IoResult<PopenConfig>

Clone the underlying PopenConfig, or return an error.

This is guaranteed not to fail as long as no Redirection::File variant is used for one of the standard streams. Otherwise, it fails if File::try_clone fails on one of the Redirections.

Trait Implementations
