Struct gdal::vector::Feature

pub struct Feature<'a> { /* fields omitted */ }

OGR Feature

Implementations

impl<'a> Feature<'a>

pub fn new(defn: &'a Defn) -> Result<Feature<'_>>

pub unsafe fn from_c_feature(
    defn: &'a Defn,
    c_feature: OGRFeatureH
) -> Feature<'_>

Creates a new Feature by wrapping a C pointer and a Defn

Safety

This method operates on a raw C pointer

pub fn _lazy_feature_geometries(defn: &'a Defn) -> Vec<Geometry>

pub fn fid(&self) -> Option<u64>

Returns the feature identifier, or None if none has been assigned.

pub fn field<S: AsRef<str>>(&self, name: S) -> Result<Option<FieldValue>>

Get the value of a named field. If the field exists, it returns a FieldValue wrapper, that you need to unpack to a base type (string, float, etc).

If the field is missing, returns GdalError::InvalidFieldName.

If the field has an unsupported type, returns a GdalError::UnhandledFieldType.

If the field is null, returns None.

pub fn geometry(&self) -> &Geometry

Get the field’s geometry.

pub fn geometry_by_name(&self, field_name: &str) -> Result<&Geometry>

pub fn geometry_by_index(&self, idx: usize) -> Result<&Geometry>

pub fn create(&self, lyr: &Layer<'_>) -> Result<()>

pub fn set_field_string(&self, field_name: &str, value: &str) -> Result<()>

pub fn set_field_double(&self, field_name: &str, value: f64) -> Result<()>

pub fn set_field_integer(&self, field_name: &str, value: i32) -> Result<()>

pub fn set_field_integer64(&self, field_name: &str, value: i64) -> Result<()>

pub fn set_field(&self, field_name: &str, value: &FieldValue) -> Result<()>

pub fn set_geometry(&mut self, geom: Geometry) -> Result<()>

pub fn field_count(&self) -> i32

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

Trait Implementations

impl<'a> Debug for Feature<'a>

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

Formats the value using the given formatter.

impl<'a> Drop for Feature<'a>

fn drop(&mut self)

Executes the destructor for this type.
