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
}

Structure designed to be passed to Popen::create.

Always create this structure using the Default trait, such as PopenConfig { field1: value1, field2: value2, ..Default::default() }. This ensures that later additions to the struct do not break existing code.

An alternative to using PopenConfig is the Exec struct which provides a builder-style interface to the same functionality.

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 this field is provided, this executable will be used to run the program instead of argv[0], but argv[0] will still be provided as the program's argument list.

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 fail if File::try_clone fails on one of the Redirection values.

try_clone().unwrap() is used to implement clone() for the builder structs Exec and Pipeline.
