Struct StdChild

pub struct StdChild(pub Child);

Available on crate feature std only.

A thin wrapper around Child.

This is used only because implementing StdChildWrapper directly on std’s Child creates loops in the type system. It is not intended to be used directly, but only to be used internally by the library.
