pub struct Wyrm { /* private fields */ }

Wyrm tile fetcher.

To create:

• Use serde to deserialize a WyrmCfg
• let wyrm = Wyrm::try_from(wyrm_cfg)?;

Implementations

impl Wyrm

pub fn query_features(&self, bbox: BBox<f64>) -> Result<(), Error>

Query features in a bounding box

pub fn fetch_tile<W: Write>( &self, out: &mut W, group_name: &str, tid: TileId ) -> Result<(), Error>

Fetch one tile.

• out Writer to write MVT data.
• group_name Name of layer group.
• tid Tile ID.
