RawMonitoredSpinlockStorage

Struct RawMonitoredSpinlockStorage 

Source
pub struct RawMonitoredSpinlockStorage { /* private fields */ }
Expand description

Opaque layout block for the Zircon C++ MonitoredSpinLock object.

Like RawSpinlockStorage, this type intentionally over-aligns to 8 bytes even when spin_lock_tracing is disabled.

Implementations§

Source§

impl RawMonitoredSpinlockStorage

Source

pub fn project<'__pin>( self: Pin<&'__pin mut Self>, ) -> RawMonitoredSpinlockStorageProjection<'__pin>
