This function calculates the distance between the first features of two layers or coordinates. Note: This function only works with proxy objects as it returns a numeric value to R.

)The proxy object for method chaining.
A mapboxgl_proxy or maplibre_proxy object.
The ID of the first layer or source (mutually exclusive with data and coordinates).
The ID of the second layer or source (required if layer_id is used).
An sf object for the first geometry (mutually exclusive with layer_id and coordinates).
A numeric vector of length 2 with lng/lat coordinates for the first point (mutually exclusive with layer_id and data).
A numeric vector of length 2 with lng/lat coordinates for the second point (required if coordinates is used).
The units for the distance calculation. One of "meters", "kilometers", "miles", etc.
Character string specifying the Shiny input ID suffix for storing the distance result. Default is "turf_distance_result". Result will be available as input[[paste0(map_id, "_turf_", input_id)]].
