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

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 unsafe fn c_feature(&self) -> OGRFeatureH

Returns the C wrapped pointer

Safety

This method returns 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 field_as_integer(&self, field_idx: i32) -> Result<Option<i32>>

Get the value of the specified field as a i32.

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

Returns Ok(None) if the field is null. Returns Ok(Some(0)) on other kinds of errors.

pub fn field_as_integer_by_name(&self, field_name: &str) -> Result<Option<i32>>

Get the value of the specified field as a i32.

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

Returns Ok(None) if the field is null. Returns Ok(Some(0)) on other kinds of errors.

pub fn field_as_integer64_by_name(&self, field_name: &str) -> Result<Option<i64>>

Get the value of the specified field as a i64.

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

Returns Ok(None) if the field is null. Returns Ok(Some(0)) on other kinds of errors.

pub fn field_as_integer64(&self, field_idx: i32) -> Result<Option<i64>>

Get the value of the specified field as a i64.

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

Returns Ok(None) if the field is null. Returns Ok(Some(0)) on other kinds of errors.

pub fn field_as_double_by_name(&self, field_name: &str) -> Result<Option<f64>>

Get the value of the specified field as a f64.

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

Returns Ok(None) if the field is null. Returns Ok(Some(0.)) on other kinds of errors.

pub fn field_as_double(&self, field_idx: i32) -> Result<Option<f64>>

Get the value of the specified field as a f64.

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

Returns Ok(None) if the field is null. Returns Ok(Some(0.)) on other kinds of errors.

pub fn field_as_string_by_name(&self, field_name: &str) -> Result<Option<String>>

Get the value of the specified field as a String.

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

Returns Ok(None) if the field is null.

pub fn field_as_string(&self, field_idx: i32) -> Result<Option<String>>

Get the value of the specified field as a String.

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

Returns Ok(None) if the field is null.

pub fn field_as_datetime_by_name(
    &self,
    field_name: &str
) -> Result<Option<DateTime<FixedOffset>>>

Get the value of the specified field as a DateTime<FixedOffset>.

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

Returns Ok(None) if the field is null.

pub fn field_as_datetime(
    &self,
    field_idx: i32
) -> Result<Option<DateTime<FixedOffset>>>

Get the value of the specified field as a DateTime<FixedOffset>.

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

Returns Ok(None) if the field is null.

pub fn geometry(&self) -> &Geometry
