Helper methods for accessing and mutating values in a VirtualStaticExtension.

These helpers operate on statically shaped extensions with array-like semantics:

• collection size is fixed at compile time
• no resizing or extension is performed
• operations act on the entire structure

Structure and types are defined externally via VirtualStaticExtensionSchema, while storage is handled by the container.

All operations are performed via tagged conversions.

Default Discriminant

• K = (): operates on a single default extension, meaning one static extension is assumed.

Provided Methods

fn get_all( &self, ) -> Option<<Self::TypesVia as VirtualStaticExtensionSchema<K>>::Many>

Retrieves the full collection (Many).

fn set_all( &mut self, v: <Self::TypesVia as VirtualStaticExtensionSchema<K>>::Many, )

where <Self::TypesVia as VirtualStaticExtensionSchema<K>>::Many: Delimited,

Sets full collection.

fn get( &self, ) -> Option<<Self::TypesVia as VirtualStaticExtensionSchema<K>>::Some>

Retrieves Some.

fn set(&mut self, v: <Self::TypesVia as VirtualStaticExtensionSchema<K>>::Some)

Sets Some.

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.

Implementors

impl<T, K> StaticExtHelpers<K> for T

where T: VirtualStaticExtension<K>, K: DiscriminantTag,

Blanket impl for all VirtualStaticExtension types.

This trait is not intended to be implemented manually. It exists as an ergonomic replacement for free helper functions.

All methods have default implementations, making this forward-compatible: new helpers can be added without breaking existing code.
