Struct SlotStorage 

pub struct SlotStorage {
    physical: Option<(ContainerRef, usize)>,
    dependencies: Vec<ContainerRef>,
}

Physical storage and auxiliary container dependencies used by a Slot.

Menu builders derive their complete lock set and physical-alias checks from this descriptor, so custom slots must include every container accessed by any slot callback.

Fields

physical: Option<(ContainerRef, usize)>

dependencies: Vec<ContainerRef>

Implementations

impl SlotStorage

pub fn physical(container: impl Into<ContainerRef>, index: usize) -> Self

Describes a slot backed by one physical container position.

pub fn virtual_slot( dependencies: impl IntoIterator<Item = impl Into<ContainerRef>>, ) -> Self

Describes a storage-less slot that only accesses auxiliary containers.

pub fn with_dependencies( self, dependencies: impl IntoIterator<Item = impl Into<ContainerRef>>, ) -> Self

Adds auxiliary containers accessed by slot callbacks.

pub fn physical_backing(&self) -> Option<(&ContainerRef, usize)>

Returns the slot’s physical container and container-local index.

pub fn physical_key(&self) -> Option<(ContainerId, usize)>

Returns the stable identity of the physical backing position.

pub(crate) fn container_refs(&self) -> impl Iterator<Item = &ContainerRef>
