Expand description

An optimized version of the Pwm trait that if your pending writes manager is depend on the order.

Required Methods§

Source

fn get_comparable<Q>( &self, key: &Q, ) -> Result<Option<&EntryValue<Self::Value>>, Self::Error>
where Self::Key: Borrow<Q>, Q: Ord + ?Sized,

Optimized version of Pwm::get that accepts borrowed keys.

Source

fn get_entry_comparable<Q>( &self, key: &Q, ) -> Result<Option<(&Self::Key, &EntryValue<Self::Value>)>, Self::Error>
where Self::Key: Borrow<Q>, Q: Ord + ?Sized,

Optimized version of Pwm::get that accepts borrowed keys.

Source

fn contains_key_comparable<Q>(&self, key: &Q) -> Result<bool, Self::Error>
where Self::Key: Borrow<Q>, Q: Ord + ?Sized,

Optimized version of Pwm::contains_key that accepts borrowed keys.

Source

fn remove_entry_comparable<Q>( &mut self, key: &Q, ) -> Result<Option<(Self::Key, EntryValue<Self::Value>)>, Self::Error>
where Self::Key: Borrow<Q>, Q: Ord + ?Sized,

Optimized version of Pwm::remove_entry that accepts borrowed keys.

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.
