Crate builderx_core 

Core traits for the builderx DSL (builder-pattern adapters).

These traits define how the bx! macro talks to concrete UI toolkits. Adapters bridge between a generic builder syntax and a specific “attach child/children” API that each toolkit exposes.

Picking an integration style

• If you control the builder type (or it already has attach semantics), implement AttachChild / AttachChildren and use DefaultAdapter for the most ergonomic path—no adapter type needed.
• If the builder is foreign or needs custom glue, implement BxAdapter + CanAttach / CanAttachMany on a small adapter type instead.

Structs

DefaultAdapter

Default adapter that delegates to AttachChild / AttachChildren. Use this when your builder already implements those extension traits.

Traits

AttachChild

Trait for builders that can accept a single child value. Implement this on your toolkit’s builder type when you want to opt into the default adapter.

AttachChildren

Trait for builders that can accept an iterator of child values. Implement alongside AttachChild to handle spread (..iter) children efficiently.

BxAdapter

Adapter hook to make the builder DSL agnostic to concrete APIs.

CanAttach

Marker/behavior for adapter-specific single-child support.

CanAttachMany

Marker/behavior for adapter-specific multi-child support.
