Trait UpgradableReadApi 

pub trait UpgradableReadApi: GuardedTarget {
    type UpgradableReadGuard<'a>: UpgradableReadGuard<Target = Self::Target>
       where Self: 'a;

    // Required method
    fn upgradable_read(&mut self) -> Self::UpgradableReadGuard<'_>;
}

Provides a constant (but upgradable) part of the RwApi interface.

Example

See the RwApi docs for usage examples.

Required Associated Types

type UpgradableReadGuard<'a>: UpgradableReadGuard<Target = Self::Target> where Self: 'a

Self::upgradable_read return type.

Required Methods

fn upgradable_read(&mut self) -> Self::UpgradableReadGuard<'_>

Generalizes RwLock::upgradable_read.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
