Hi I am new to rust can i give it a try

Here are some details for the implementation:

1. Since OSM requires the attribution to contain a link to their site, it would be a good idea to make the new method return a struct, that will contain attribution text and an optional url to link to.
2. The correct attribution for OSM should be added to the RasterTileLayer::with_osm() method and to the examples in docs that use OSM url. Some of those example can be replaced with the with_osm() method (they were written before this method existed).
3. It would be great to check MapTiler term and conditions and if they require attribution (I am almost sure they do), add it to the vector tile examples.

Don't hesitate to ask if you have any questions.

Thanks for the suggestions. Please bare with me.
We can have a attribution() method in Layers which we can use for Vector, raster and features.
I tried to understand the code starting from raster_tile.rs example ( went back to all function calls and definitions of what is happening)

I am not getting how can we render/ show this on map.

1. Tried adding attribution on RasterTileLayer like:

pub fn new(
        tile_schema: TileSchema,
        tile_provider: impl RasterTileProvider + 'static,
        messenger: Option<Arc<dyn Messenger>>,
    ) -> Self {
           
          Self {
            tile_provider: Arc::new(tile_provider),
            tile_schema,
            prev_drawn_tiles: Mutex::new(vec![]),
            fade_in_duration: Duration::from_millis(300),
            tiles: Arc::new(Cache::new(5000)),
            messenger,
            attribution: Self::with_osm(),
        }
    }

fn with_osm()-> Attribution {
        Attribution {
            text: "© OpenStreetMap contributors",
            url: "https://www.openstreetmap.org/copyright",
        }
    }


impl Layers for RasterTileLayer{
.
.

fn attribution(&self) -> Attribution {
        self.attribution.clone()
        
    }
}

2. MapTiler does require the attribution once i get this one right i will do that as well

Could you please point me to right direction I think i am missing a lot here

Displaying attribution on the map is not the work of the Map per se, but of the UI environment that draws the map. In case of our examples, we use integration with egui by the EguiMap in the galileo-egui crate. To add the attribution text, add a new ui.label() at the end of .render method. You can see some examples of how to use egui in the egui-app example, or go to their demo.
