Struct gdal::vector::Defn

pub struct Defn { /* private fields */ }

Layer definition

Defines the fields available for features in a layer.

Implementations

impl Defn

pub unsafe fn from_c_defn(c_defn: OGRFeatureDefnH) -> Defn

Creates a new Defn by wrapping a C pointer

Safety

This method operates on a raw C pointer

pub unsafe fn c_defn(&self) -> OGRFeatureDefnH

Returns the wrapped C pointer

Safety

This method returns a raw C pointer

pub fn fields(&self) -> FieldIterator<'_>

Iterate over the field schema of this layer.

pub fn geom_fields(&self) -> GeomFieldIterator<'_>

Iterate over the geometry field schema of this layer.

pub fn from_layer<L: LayerAccess>(lyr: &L) -> Defn
