Crate snapr 

Snapr

Snapr (/ˈsnæp ər/) is a library that enables a flexible and frictionless way to render snapshots of maps with overlayed geometries.

Examples

• Open Street Maps - Collection of binaries using an OSM tile fetcher.
  • Point - Example showing how to draw a point geometry.
  • Line - Example showing how to draw a line geometry.
  • Line String - Example showing how to draw a line string geometry.
  • Polygon - Example showing how to draw a polygon geometry.
• Labels - Example showing how to label a point geometry.
• SVGs - Example showing how to draw an SVG on top of a point geometry.
• Batch - Example showing how to use a TileFetcher::Batch, as opposed to the usual TileFetcher::Individual variant.
• Stateful - Example showing how to implement the IndividualTileFetcher trait to enable a TileFetcher that keeps track of state.
• Tokio - Example showing how to use the tokio feature flag to build an asynchronous TileFetcher.
