Type Parameters

Type Parameter	Description
R extends Record<string, any>	A record describing the data item entry to get. The record should contain a property whose name is equal to the label of the data item entry, and the type of the property defines the value type of the data item entry.
L extends string	The label of the data item entry to get.

Parameters

Parameter	Type	Description
label	L	The label of the data item entry to get.
index	number	The index of the data item entry to get.

Returns

DataItemEntry<R[L]>

The requested data item entry.
