# Zoom in maplibre::coords - Rust
`Zoom` is an exponential scale that defines the zoom of the camera on the map. We can derive the `ZoomLevel` from `Zoom` by using the `[crate::coords::ZOOM_BOUNDS]`.

Expand description

`Zoom` is an exponential scale that defines the zoom of the camera on the map. We can derive the `ZoomLevel` from `Zoom` by using the `[crate::coords::ZOOM_BOUNDS]`.

## Implementations§

source §

### impl Zoom

source

#### pub fn new(zoom: f64) -> Self

source §

### impl Zoom

source

#### pub fn from(zoom_level: ZoomLevel) -> Self

source §

### impl Zoom

source

#### pub fn scale_to_tile(&self, coords: &WorldTileCoords) -> f64

source

#### pub fn scale_to_zoom_level(&self, z: ZoomLevel) -> f64

source

#### pub fn scale_delta(&self, zoom: &Zoom) -> f64

source

#### pub fn zoom_level(&self, tile_size: f64) -> ZoomLevel

Adopted from Transform::coveringZoomLevel

This function calculates which ZoomLevel to show at this zoom.

The `tile_size` is the size of the tile like specified in the source definition, For example raster tiles can be 512px or 256px. If it is 256px, then 2x as many tiles are displayed. If the raster tile is 512px then exactly as many raster tiles like vector tiles would be displayed.
