Struct vmcore::vmtime::VmTimeSourceBuilder

pub struct VmTimeSourceBuilder { /* private fields */ }

A time source builder, used to spawn tasks that back VmTimeSource instances.

Note that this can be sent across processes via mesh.

However, the time keeping infrastructure assumes that all time keeping tasks share a single global monotonic OS clock. This means that if you send this across a VM/kernel/network boundary, the resulting time sources will not be in sync with each other.

Implementations

impl VmTimeSourceBuilder

pub async fn build( &self, driver: &impl SpawnDriver, ) -> Result<VmTimeSource, TimeKeeperIsGone>

Builds and spawns a backing task for VmTimeSources. All VmTimeSource instances cloned from the first one will share a backing task.
