Enum ProcessPriority 

#[non_exhaustive]
pub enum ProcessPriority {
    Normal,
    BelowNormal,
    Idle,
}

Scheduling priority requested for the child. Normal (the default) means “inherit”: it leaves the spawn exactly as it was before this option existed, so the child keeps the parent’s priority class (Windows) or nice value (Unix). It does not reset a lowered parent back to normal. The other values only lower priority, which needs no privilege and never raises a value the child already inherits above a lower one.

Windows: BelowNormal adds BELOW_NORMAL_PRIORITY_CLASS and Idle adds IDLE_PRIORITY_CLASS to the creation flags. Unix: the child’s nice value is raised to at least 10 (BelowNormal) or 19 (Idle) between fork and exec.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
