Expand description
Thread priority enumeration.
Variants
Min
Holds a value representing the minimum possible priority.
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.
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.
Implementations
Returns the maximum allowed value for using with the provided policy. The returned number is in the range of allowed values.
Returns the minimum allowed value for using with the provided policy. The returned number is in the range of allowed values.

) -> Result<c_int, Error>
pub fn to_allowed_value_for_policy(
priority: c_int,
policy: ThreadSchedulePolicy
) -> Result<c_int, Error>
Checks that the passed priority value is within the range of allowed values for using with the provided policy.
Converts the priority stored to a posix number. POSIX value can not be known without knowing the scheduling policy https://linux.die.net/man/2/sched_get_priority_max
Gets priority value from POSIX value. In order to interpret it correctly, you should also take scheduling policy into account.
Sets current thread’s priority to this value.
