Trait PanelBuilder 

pub trait PanelBuilder {
    // Required method
    fn build(&mut self, state: &PanelState, info: &PanelInfo) -> PanelId;
}

Everything gpui_base::dock exports, so a consumer never has to depend on the foundation crate directly to write a skin or read a container’s state. Kept in step with base’s own list by every_base_dock_export_is_reachable_from_here.

Two names are handled elsewhere and one is deliberately absent: base’s Panel and PanelView arrive as BasePanel and BasePanelView because this module’s Panel/PanelView are the presentation halves that extend them, and base’s Dock — a plain state struct holding one dock’s open, collapsible, size and resizing flags — is not re-exported at all, because the name meant a panel container in every released version of this crate and handing it back with a different meaning is worse than dropping it. A skin reads a dock through DockContext. Turns a persisted leaf into a live panel id.

The production implementation (at the gpui-component layer, above this crate) consults PanelRegistry and falls back to an invalid-panel placeholder that retains the original PanelState, so a panel type this build does not know about survives a load/save round trip instead of being erased.

Required Methods

Dyn Compatibility

This trait is dyn compatible.

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