Trait DowngradableWriteGuard

pub trait DowngradableWriteGuard: DerefMut {
    type DowngradeResult: Deref<Target = Self::Target>;
    type DowngradeToUpgradableResult: UpgradableReadGuard<UpgradeToDowngradableResult = Self, Target = Self::Target>;

    // Required methods
    fn downgrade(self) -> Self::DowngradeResult;
    fn downgrade_to_upgradable(self) -> Self::DowngradeToUpgradableResult;
}

Provides an interface for downgrading downgradable write guards.

Example

See the GuardedTarget docs for implementation examples.

Required Associated Types

type DowngradeResult: Deref<Target = Self::Target>

Self::downgrade return type.

type DowngradeToUpgradableResult: UpgradableReadGuard<UpgradeToDowngradableResult = Self, Target = Self::Target>

Self::downgrade_to_upgradable return type.

Required Methods

fn downgrade(self) -> Self::DowngradeResult

Downgrades the write guard to a read guard.

fn downgrade_to_upgradable(self) -> Self::DowngradeToUpgradableResult

Downgrades the write guard to an upgradable read guard.
