Usage example ```rust use tokio; use anyhow::Result;

use geosuggestcore::{Engine, EngineDumpFormat}; use geosuggestutils::{IndexUpdater, IndexUpdaterSettings};

[tokio::main]

async fn main() -> Result<()> { println!("Build index..."); let engine = load_engine().await?;

println!(
    "Suggest result: {:#?}",
    engine.suggest::<&str>("Beverley", 1, None, Some(&["us"]))
);
println!(
    "Reverse result: {:#?}",
    engine.reverse::<&str>((11.138298, 57.510973), 1, None, None)
);

Ok(())

}

async fn loadengine() -> Result { let indexfile = std::path::Path::new("/tmp/geosuggest-index.bincode");

let updater = IndexUpdater::new(IndexUpdaterSettings {
    names: None, // no multilang support
    ..Default::default()
})?;

Ok(if index_file.exists() {
    // load existed index
    let engine = Engine::load_from(index_file, EngineDumpFormat::Bincode)
        .map_err(|e| anyhow::anyhow!("On load index file: {e}"))?;

    if updater.has_updates(&engine).await? {
        // rewrite index file
        let engine = updater.build().await?;
        engine.dump_to(index_file, EngineDumpFormat::Bincode)?;
        engine

} else {

    let engine = updater.build().await?;
