Enum command_group::stdlib::ErasedChild

pub enum ErasedChild {
    Grouped(GroupChild),
    Ungrouped(Child),
}

Wrapper around a process child, be it grouped or ungrouped.

This is a helper which erases that a std::process::Child is a different type than a GroupChild. It forwards to the corresponding method on the inner type.

Variants

Grouped(GroupChild)

A grouped process child.

Ungrouped(Child)

An ungrouped process child.
