Trait RawRwLockDowngrade

pub unsafe trait RawRwLockDowngrade: RawRwLock {
    // Required method
    unsafe fn downgrade(&self);
}

Additional methods for RwLocks which support atomically downgrading an exclusive lock to a shared lock.

Required Methods

unsafe fn downgrade(&self)

Atomically downgrades an exclusive lock into a shared lock without allowing any thread to take an exclusive lock in the meantime.

Safety

This method may only be called if an exclusive lock is held in the current context.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
