Enum ubend::Error

pub enum Error {
    OS(c_int),

    CannotRedirectStdinTo(Target),
    NotEnoughPipes,

}

Variants

OS(c_int)

A libc function returned an error of specified errno.

NotEnoughArguments

Any command needs to have at least one "argument" (the command name).

CannotRedirectStdinTo(Target)

stdin cannot be redirected to stderr or stdout, since those are output streams and stdin is an input stream.

NotEnoughPipes

A pipe chain has to have at least one command.

InvalidPipeLinkup

If stdin of a child process is marked as PipeSetup::Pipe then stdout of the previous process in the chain has to be PipeSetup::Pipe or PipeSetup::Redirect(Target::Stdout) or stderr of that previous process has to be PipeSetup::Redirect(Target::Stdout).
