  summary: >-
    A cost function for a given pair of neighboring path finding positions.

    If a path point should have the default cost, <xref href="MLEM.Pathfinding.AStar%601.DefaultCost" data-throw-if-not-resolved="false"></xref> should be returned.

    If a path point should be unreachable, <xref href="System.Single.PositiveInfinity" data-throw-if-not-resolved="false"></xref> or <xref href="System.Single.MaxValue" data-throw-if-not-resolved="false"></xref> should be returned.
  example: []
  syntax:

      description: The current position in the path.
    - id: nextPos
      type: '{T}'
      description: The neighboring position whose cost to check.
