Enum thread_priority::ThreadPriority

pub enum ThreadPriority {
    Min,
    Crossplatform(ThreadPriorityValue),
    Os(ThreadPriorityOsValue),
    Max,
}

Thread priority enumeration.

Variants

Min

Holds a value representing the minimum possible priority. The ThreadPriority::Min value is mapped to WinAPIThreadPriority::Lowest and not WinAPIThreadPriority::Idle to avoid unexpected drawbacks. Use the specific value to set it to WinAPIThreadPriority::Idle when it is really needed.

Crossplatform(ThreadPriorityValue)

Holds a platform-independent priority value. Usually used when setting a value, for sometimes it is not possible to map the operating system’s priority to this value.

Os(ThreadPriorityOsValue)

Holds an operating system specific value. If it is not possible to obtain the ThreadPriority::Crossplatform variant of the value, this is returned instead. The value is matched among possible values in Windows from WinAPIThreadPriority::Idle till WinAPIThreadPriority::TimeCritical. This is due to windows only having from 7 to 9 possible thread priorities and not 100 as it is allowed to have in the ThreadPriority::Crossplatform variant.

Max

Holds a value representing the maximum possible priority. Should be used with caution, it solely depends on the target os where the program is going to be running on, how it will behave. On some systems, the whole system may become frozen if not used properly. The ThreadPriority::Max value is mapped to WinAPIThreadPriority::Highest and not WinAPIThreadPriority::TimeCritical to avoid unexpected drawbacks. Use the specific value to set it to WinAPIThreadPriority::TimeCritical when it is really needed.
