Struct TraceBase

Source 
#[repr(C)]
pub struct TraceBase {
    pub end: AtomicU64,
    pub start: u64,
}
Expand description

The base structure for a trace object.

Fields§

§end: AtomicU64

The end point for valid data. The kernel will update this and submit a thread_sync wakeup when writing trace data to this object.

§start: u64

The start point of valid data in this object. This is set by the kernel during initialization and then not updated again.

Implementations§

Source§

impl TraceBase

Source

pub fn waiter(&self, pos: u64) -> ThreadSyncSleep
