Struct GeometryCollectionCapacity

pub struct GeometryCollectionCapacity { /* private fields */ }

A counter for the buffer sizes of a GeometryCollectionArray.

This can be used to reduce allocations by allocating once for exactly the array size you need.

Implementations

impl GeometryCollectionCapacity

pub fn new(mixed_capacity: MixedCapacity, geom_capacity: usize) -> Self

Create a new capacity with known sizes.

pub fn new_empty() -> Self

Create a new empty capacity.

pub fn is_empty(&self) -> bool

Return true if the capacity is empty.

pub fn geom_capacity(&self) -> usize

The geometry offset buffer capacity

pub fn add_geometry<T: WktNum>( &mut self, geom: Option<&impl GeometryTrait<T = T>>, ) -> GeoArrowResult<()>

Add a Geometry to this capacity counter.

pub fn add_geometry_collection<'a, T: WktNum>( &mut self, geom: Option<&'a (impl GeometryCollectionTrait<T = T> + 'a)>, ) -> GeoArrowResult<()>

Add a GeometryCollection to this capacity counter.

pub fn from_geometry_collections<'a, T: WktNum>( geoms: impl Iterator<Item = Option<&'a (impl GeometryCollectionTrait<T = T> + 'a)>>, ) -> GeoArrowResult<Self>

Create a capacity counter from an iterator of GeometryCollections.

pub fn from_geometries<'a, T: WktNum>( geoms: impl Iterator<Item = Option<&'a (impl GeometryTrait<T = T> + 'a)>>, ) -> GeoArrowResult<Self>

Create a capacity counter from an iterator of Geometries.

pub fn num_bytes(&self) -> usize

The number of bytes an array with this capacity would occupy.
