Struct JobObject

pub struct JobObject;

Available on Windows and crate feature job-object and crate feature std only.

Wrapper which creates a job object context for a Command.

This wrapper is only available on Windows.

It creates a Windows Job Object and associates the Command to it. This behaves analogously to process groups on Unix or even cgroups on Linux, with the ability to restrict resource use. See Job Objects.

This wrapper provides a child wrapper: JobObjectChild.

When both CreationFlags and JobObject are used together, either:

• CreationFlags must come first, or
• CreationFlags must include CREATE_SUSPENDED
