Required Methods§

Source

fn value_clear<T: Value, IK: Metakey, N: Metakey>( &self, handle: &Handle<ValueState<T>, IK, N>, ) -> Result<()>

Source

fn value_get<T: Value, IK: Metakey, N: Metakey>( &self, handle: &Handle<ValueState<T>, IK, N>, ) -> Result<Option<T>>

Source

fn value_set<T: Value, IK: Metakey, N: Metakey>( &self, handle: &Handle<ValueState<T>, IK, N>, value: T, ) -> Result<Option<T>>

Source

fn value_fast_set<T: Value, IK: Metakey, N: Metakey>( &self, handle: &Handle<ValueState<T>, IK, N>, value: T, ) -> Result<()>

Source

fn value_fast_set_by_ref<T: Value, IK: Metakey, N: Metakey>( &self, handle: &Handle<ValueState<T>, IK, N>, value: &T, ) -> Result<()>

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.
