Constructs a ComponentSlot | | Takes: | - the slot address label | - the slot address index | - the component for the slot | - the input value to pass to the component | - a function mapping outputs from the component to a query in the parent

A default value for mkEval that will result in an eval that nothing at | all - all incoming actions and queries will be ignored, and no receiver, | initializer, or finalizer will be specified. | | Usually this will be used with record update syntax to override fields to | specify things as needed. If a component only needs to handle actions, | for instance, a usage might be something like this: | | ```purescript | H.mkComponent | { initialState | , render | , eval: H.mkEval (H.defaultEval { handleAction = ?handleAction }) | } | ```

Changes the Component's m type. A use case for this | might be to interpret some Free monad as IO so the component can be | used with runUI.

Accepts an EvalSpec to produce an eval function for a component. For | example: | | ```purescript | -- use defaultEval and override fields selectively | H.mkEval (H.defaultEval { handleAction = ?handleAction }) | | -- or specify all the fields in the EvalSpec | H.mkEval | { handleAction: ?handleAction | , handleQuery: ?handleQuery | , receive: ?receive | , initialize: ?initialize | , finalize: ?finalize | } | ```

The spec record that mkEval accepts to construct a component eval | function. | | It's not a requirement to use mkEval, and sometimes it's preferrable | to write a component eval function from scratch, but often mkEval is | more convenient for common cases. | | See below for more details about mkEval and defaultEval.

A convenience synonym for the output type of a render function for a | component that renders HTML. | | - action is the type of actions, events internal to the component that can | be evaluated with the handleAction function | - slots is the set of child component types that can be used in the HTML | - m is the monad used by the child component during evaluation
