Struct TabGroupConstraints 

pub struct TabGroupConstraints { /* private fields */ }

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. Everything the container knows about a group’s place in the dock.

Pushed as one value rather than one setter per fact. These are read together, and a container that updates one while leaving another stale describes a dock that cannot exist — a group on a tiles canvas that still reports itself droppable, or a group beside siblings that still reports itself alone. Choosing a constructor forces the container kind to be stated; anything a constructor does not grant stays off, so a container that forgets something gets a group that does less rather than more.

Implementations

impl TabGroupConstraints

pub fn sealed() -> TabGroupConstraints

A group with nowhere to go: locked, alone, unclosable. What a group starts as, before any container has placed it.

pub fn in_split(alone: bool) -> TabGroupConstraints

A group in a split layout. alone when nothing sits beside it, which is what stops its last visible panel being dragged out and leaving the dock empty.

pub fn dock_locked(self, dock_locked: bool) -> TabGroupConstraints

Whether the dock as a whole forbids rearranging.

pub fn collapsed(self, collapsed: bool) -> TabGroupConstraints

Whether the group is folded away to a strip of tabs with no content.

pub fn closable(self, closable: bool) -> TabGroupConstraints

Whether the container allows this group’s panels to be closed at all. A dock’s last group sets this false so the dock cannot be emptied.

pub fn is_alone(&self) -> bool

Whether nothing sits beside this group in its tree.

pub fn is_locked(&self) -> bool

Whether the group’s place in the dock is fixed.

The dock-wide lock is the whole of it. A tab group only ever sits inside a split — a tiles canvas holds panels directly and never a tab group — so there is no second way for a container to pin one down, and no separate is_dock_locked reader that would answer identically.
