substring<EntityT extends EntityBase>(
    str:
        | string
        | Field<EntityT, boolean, boolean>
        | StringFilterFunction<EntityT>,
    pos:
        | number
        | Field<EntityT, boolean, boolean>
        | NumberFilterFunction<EntityT>,
    len?:
        | number
        | Field<EntityT, boolean, boolean>
        | NumberFilterFunction<EntityT>,
): StringFilterFunction<EntityT>
Internal
Build a filter function to get a substring starting from a designated position. Evaluates to string.
Type Parameters
- EntityT extends EntityBase
Parameters
- str: string | Field<EntityT, boolean, boolean> | StringFilterFunction<EntityT>
  The string to get a substring from. This can either be a string, a reference to a field or another filter function.
- pos: number | Field<EntityT, boolean, boolean> | NumberFilterFunction<EntityT>
  The starting position of the substring. This can be either a number, a reference to a field or another filter function.
- Optionallen: number | Field<EntityT, boolean, boolean> | NumberFilterFunction<EntityT>
  The length of the substring. This can be either a number, a reference to a field or another filter function.
Returns StringFilterFunction<EntityT>
The newly created filter function
