Implementations

impl SchedulerManager

pub fn new(role_overrides: RoleOverrides) -> SchedulerManager

pub fn empty_for_tests() -> Self

Create a new empty SchedulerManager for testing.

pub fn role_name(&self, task: &Task) -> Result<&str, Errno>

Return the currently active role name for this task. Requires read access to task’s state, should only be called by code which is not already modifying the provided task.

pub fn set_thread_role( &self, task: &Task, scheduler_state: SchedulerState, ) -> Result<(), Errno>

Give the provided task’s Zircon thread a role.

Requires passing the current SchedulerState so that this can be performed without touching task’s state lock.
