Struct RemoteSource 

pub struct RemoteSource { /* private fields */ }

Remote mirror + on-disk cache, replicating SRTM.py’s default behavior.

The mirror lists .hgt.zip files under region subdirectories; we scrape the whole index once (8-ish requests) and memoize it. Tiles land in cache_dir as plain .hgt files, so a DirSource pointed at the same directory shares the cache.

Implementations

impl RemoteSource

pub fn new(base_urls: &[&str], cache_dir: impl Into<PathBuf>) -> Result<Self>

pub fn default_paths() -> Result<Self>

Default mirror and default_cache_dir.

pub fn index(&self) -> Result<HashMap<String, String>>

pub fn load_or_download(&self, lat_lo: i32, lon_lo: i32) -> Result<Arc<Tile>>
