Struct SingleLayerDataset 

pub struct SingleLayerDataset<L: Layer> {
    pub inner: Arc<L>,
    pub name: String,
}

Adapter that wraps any Layer in a Dataset facade with one sentinel layer name. Use this when a single-layer format like Shapefile needs to satisfy a Dataset interface.

Fields

inner: Arc<L>

The wrapped layer. Arc so the adapter is cheap to clone and the closure inside open_layer can hand out a borrowed reference.

name: String

The synthetic layer name surfaced via Dataset::layer_names. Default "default".

Implementations

impl<L: Layer> SingleLayerDataset<L>

pub fn new(layer: L) -> Self

pub fn with_name(layer: L, name: impl Into<String>) -> Self

Trait Implementations

impl<L: Layer + 'static> Dataset for SingleLayerDataset<L>

fn layer_names(&self) -> Vec<String>

Names of the user-facing layers in deterministic order.

fn open_layer<'a>(&'a self, name: &str) -> Result<Box<dyn Layer + 'a>>

Open the layer with the given name. Returns Error::LayerNotFound if the name isn’t present.

impl<L: Debug + Layer> Debug for SingleLayerDataset<L>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
