Struct FeatureRef 

pub struct FeatureRef<'feat, 'layer: 'feat> {
    pub id: Option<u64>,
    pub geometry: Geometry<i32>,
    /* private fields */
}

A single map feature returned by ParsedLayer01::iter_features.

Borrows values from the outer Layer01FeatureIter buffer — it must be dropped before calling LendingIterator::next again.

Fields

id: Option<u64>

Optional feature ID.

geometry: Geometry<i32>

Geometry in Geometry<i32> form (owned, decoded on demand by the iterator).

Implementations

impl<'feat, 'layer: 'feat> FeatureRef<'feat, 'layer>

pub fn iter_all_properties( &self, ) -> impl Iterator<Item = Option<PropValueRef<'layer>>> + '_

Iterate over every property slot for this feature, values only, in column order.

Yields Option<PropValueRef>:

• Some(value) — the slot contains a non-null value.
• None — the slot is null / absent.

Use Layer01::iterate_prop_names to pair values with their column names.

pub fn iter_properties(&self) -> impl Iterator<Item = ColumnRef<'layer>> + '_

Iterate over all non-null properties for this feature.

SharedDict columns are transparently expanded into one ColumnRef per sub-item. Null / absent values are skipped entirely. The iterator is infallible.

pub fn get_property(&self, name: &str) -> Option<PropValueRef<'layer>>

Look up a property by name, returning its value if present and non-null.

For SharedDict columns the expected name is "{prefix}{suffix}", matching the key used by iter_properties.

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

Formats the value using the given formatter.
