Struct LockedCommon 

#[non_exhaustive]
pub struct LockedCommon<'wait_list, L: Lock, I, O> {
    pub wait_list: &'wait_list WaitList<L, I, O>,
}

Common functions that can work on both exclusive and shared locks.

You can never create nor hold an instance of this type — it is accessed solely through the Deref implementations of LockedShared and LockedExclusive.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

wait_list: &'wait_list WaitList<L, I, O>

The list this type locks.

Implementations

impl<'wait_list, L: Lock, I, O> LockedCommon<'wait_list, L, I, O>

pub fn is_empty(&self) -> bool

Check whether there are any futures waiting in this list.

pub fn head_input(&self) -> Option<&I>

Retrieve a shared reference to the input given by the head entry in the list, if there is one.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
