source ·
pub struct Process {
    pub tasks: HashMap<Pid, Process>,
    /* private fields */
}
Expand description

Struct containing information of a process.

§iOS

This information cannot be retrieved on iOS due to sandboxing.

§Apple app store

If you are building a macOS Apple app store, it won’t be able to retrieve this information.

Fields§

§tasks: HashMap<Pid, Process>

Tasks run by this process.
