MakePipe

Use a pipe to the input or output of the child process

Fd(FileDesc)

Use an existing file descriptor as the stdio stream

Implementations

impl Stdio

pub fn to_child_stdio( &self, readable: bool, ) -> Result<(ChildStdio, Option<AnonPipe>)>

pub fn piped() -> Stdio

Create a pipe for this file descriptor and use it in the child process as the given file descriptor to facilitate input or output redirection. See MemFdExecutable::stdin for an example.

pub fn null() -> Stdio

Use a null file descriptor, like /dev/null, to either provide no input or to discard output. See MemFdExecutable::stdout for an example.

pub fn inherit() -> Stdio

Inherit the parent’s file descriptor. this is the default behavior, but is generally not the desired behavior.
