Props

Prop	Type	Default	Description
toast	LayerToastConfig	—	Toast viewport configuration: position, maxVisible, and a toast-only inset that overrides the provider inset per edge for toasts shown through useToast().
inset	LayerInset	every edge 0	A persistent bar floating over a viewport edge, declared once: blockStart, blockEnd, inlineStart, inlineEnd as pixel numbers or CSS lengths. Each edge adds to the gutter every anchored layer keeps from that edge and moves the toast viewport by the same amount.

Slots

Slot	Description
default	Application subtree that can use the shared layer context.

LayerToastConfig

Field	Type	Default	Description
position	ToastPlacement	'bottom-end'	Corner the toast viewport sits in: top-start, top-center, top-end, bottom-start, bottom-center, or bottom-end. A placement on ToastViewport still wins.
maxVisible	number	no limit	How many toasts stay on screen at once. When more are queued, only the newest ones render.
inset	LayerInset	—	Per-edge offset for the toast viewport only. An edge written here replaces the provider inset for that edge; edges left out keep the provider value.

LayerInset

Field	Type	Description
blockStart	number | string	Offset added to the gutter at the top edge. A number is pixels; a string is any CSS length, such as '4rem' or 'env(safe-area-inset-top, 0px)'.
blockEnd	number | string	Same, for the bottom edge.
inlineStart	number | string	Same, for the inline-start edge.
inlineEnd	number | string	Same, for the inline-end edge.

Exports

Export	Type	Description
useLayerConfig	() => ComputedRef<LayerContextValue> | null	The nearest provider configuration, or null outside one.
useLayerGutter	() => ComputedRef<LayerGutter>	Distance an anchored layer keeps from each viewport edge: the larger of the spacing-4 step and the device safe area, plus the provider inset.
resolveInset	(inset?: LayerInset) => ResolvedLayerInset	Turns an inset into pixels.
mergeInset	(primary?: LayerInset, fallback?: LayerInset) => ResolvedLayerInset	Merges two insets edge by edge: an edge set on primary wins, the rest come from fallback.

Native attributes

The component renders no element of its own, so class and style are not forwarded.
