Slot

Template Slot

Implementations§

source§

impl EntityReference

source

pub fn euid(euid: EntityUID) -> Self

Create an entity reference to a specific EntityUID

source

pub fn into_euid( self, slot: SlotId ) -> Result<Arc<EntityUID>, UnexpectedSlotError>

Get the entity reference as an EntityUID, returning an error if it is a slot rather than an EntityUID.

slot indicates what SlotId would be implied by EntityReference::Slot, which is always clear from the caller’s context. It is only used for error reporting

source

pub fn into_expr(&self, slot: SlotId) -> Expr

Transform into an expression AST

slot indicates what SlotId would be implied by EntityReference::Slot, which is always clear from the caller’s context.
