Struct kernel::sync::SeqLockReadGuard

source · [−]

pub struct SeqLockReadGuard<'a, L: Lock + ?Sized> { /* private fields */ }

Expand description

Allows read-side access to data protected by a sequential lock.

Implementations

source

impl<L: Lock + ?Sized> SeqLockReadGuard<'_, L>

source

pub fn need_retry(&self) -> bool

Determine if the callers needs to retry reading values.

It returns true when a concurrent writer ran between the guard being created and Self::need_retry being called.

Trait Implementations

source

impl<L: Lock + ?Sized> Deref for SeqLockReadGuard<'_, L>

type Target = <L as Lock<WriteLock>>::Inner

The resulting type after dereferencing.

source

fn deref(&self) -> &Self::Target

Dereferences the value.
