FlatGeobuf for Rust

Rust implementation of FlatGeobuf.

FlatGeobuf is a performant binary encoding for geographic data based on flatbuffers that can hold a collection of Simple Features including circular interpolations as defined by SQL-MM Part 3.

Usage

```rust use flatgeobuf::*;

let mut filein = BufReader::new(File::open("countries.fgb")?); let mut fgb = FgbReader::open(&mut filein)?; fgb.selectall()?; while let Some(feature) = fgb.next()? { println!("{}", feature.property::("name").unwrap()); println!("{}", feature.tojson()?); } ```

With async HTTP client: ```rust use flatgeobuf::*;

let mut fgb = HttpFgbReader::open("https://flatgeobuf.org/test/data/countries.fgb").await?; fgb.selectbbox(8.8, 47.2, 9.5, 55.3).await?; while let Some(feature) = fgb.next().await? { let props = feature.properties()?; println!("{}", props["name"]); println!("{}", feature.towkt()?); } ```
