Struct vmcore::vm_task::VmTaskDriver

pub struct VmTaskDriver { /* private fields */ }

A driver returned by VmTaskDriverSource.

This can be used to spawn tasks (via Spawn) and issue async IO (via Driver).

Implementations

impl VmTaskDriver

pub fn retarget_vp(&self, target_vp: u32)

Updates the target VP for the task.

pub fn is_target_vp_ready(&self) -> bool

Returns whether the target VP is ready for tasks and IO.

A driver must be operable even if this is false, but the tasks and IO may run on a different target VP.

pub async fn wait_target_vp_ready(&self)

Waits for the target VP to be ready for tasks and IO.
