Enum OutDest

pub enum OutDest {
    Pipe,
    PipeSeparate,
    Value,
    Null,
    Inherit,
    Print,
    File(Arc<File>),
}

Describes where to direct the stdout or stderr output stream of external command to.

Variants

Pipe

Redirect the stdout and/or stderr of one command as the input for the next command in the pipeline.

The output pipe will be available as the stdout of ChildProcess.

If stdout and stderr are both set to Pipe, then they will combined into the stdout of ChildProcess.

PipeSeparate

Redirect the stdout and/or stderr of one command as the input for the next command in the pipeline.

The output stream(s) will be available in the stdout or stderr of ChildProcess.

This is similar to Pipe but will never combine stdout and stderr or place an external command’s stderr into stdout of ChildProcess.

Value

Signifies the result of the pipeline will be immediately collected into a value after this command.

So, it is fine to collect the stream ahead of time in the current command.

Null

Ignore output.

This will forward output to the null device for the platform.

Inherit

Output to nushell’s stdout or stderr (only for external commands).

This causes external commands to inherit nushell’s stdout or stderr. This also causes ListStreams to be drained, but not to be printed.

Print

Print to nushell’s stdout or stderr.

This is just like Inherit, except that ListStreams and Values are also printed.

File(Arc<File>)

Redirect output to a file.
