Enum CallbackPriority 

pub enum CallbackPriority {
    High,
    Normal,
    Low,
}

Priority at which the thread pool schedules callbacks created with a CallbackEnviron.

Win32 types the priority as TP_CALLBACK_PRIORITY, an open integer alias whose only defined values are the three below; a fourth constant, TP_CALLBACK_PRIORITY_INVALID, is a count sentinel rather than a priority. This crate owns its priority surface as a closed enum so safe code cannot hand an out-of-contract value to native object creation – the very thing the bare alias would allow.

Variants

High

Highest scheduling priority (TP_CALLBACK_PRIORITY_HIGH).

Normal

Default scheduling priority (TP_CALLBACK_PRIORITY_NORMAL); the value a freshly initialized environment carries.

Low

Lowest scheduling priority (TP_CALLBACK_PRIORITY_LOW).
