Hey I am newbee to gdal. I have this code.

fn main() {
    use gdal::{Dataset, Metadata};
    use std::path::Path;

    let driver = gdal::DriverManager::get_driver_by_name("ESRI Shapefile").unwrap();
    println!("driver description: {:?}", driver.description());

    let path = Path::new("/home/yuyang/Downloads/map.shp");
    let dataset = Dataset::open(path).unwrap();
    println!("dataset description: {:?}", dataset.description());

    let key = "INTERLEAVE";
    let domain = "IMAGE_STRUCTURE";
    let meta = dataset.metadata_item(key, domain);
    println!("domain: {domain:?} key: {key:?} -> value: {meta:?}");
}

driver description: Ok("ESRI Shapefile")

I have this file

yuyang@yuyang-virtual-machine:~/sometests/gdal_test$ file /home/yuyang/Downloads/map.shp 
/home/yuyang/Downloads/map.shp: ESRI Shapefile version 1000 length 170042 type Polygon

Shapefiles are actually sets of multiple files. You don't need the shx, as the message says, but you're still going to miss the attributes. It would be best to ask for the full set of files.

And if you run ogrinfo, you'll get the same error.

@lnicola Thanks。
