Struct WkbMetadata 

pub struct WkbMetadata {
    pub crs: Option<Value>,
    pub algorithm: Option<Edges>,
}

The metadata associated with a WkbType.

Fields

crs: Option<Value>

The Coordinate Reference System (CRS) of the WkbType, if present.

This may be a raw string value (e.g., “EPSG:3857”) or a JSON object (e.g., PROJJSON). Note: Common lon/lat CRS representations (EPSG:4326, OGC:CRS84) are canonicalized to None during serialization to match Parquet conventions.

algorithm: Option<Edges>

The edge interpolation algorithm of the WkbType, if present.

Implementations

impl Metadata

pub fn new(crs: Option<&str>, algorithm: Option<Edges>) -> Self

Constructs a new Metadata with the given CRS and algorithm.

If a CRS is provided, and can be parsed as JSON, it will be stored as a JSON object instead of its string representation.

pub fn type_hint(&self) -> Hint

Returns a Hint to the likely underlying Logical Type that this Metadata represents.

fn crs_is_lon_lat(&self) -> bool

Detect if the CRS is a common representation of lon/lat on the standard WGS84 ellipsoid

Trait Implementations

impl Clone for Metadata

fn clone(&self) -> Metadata

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Metadata

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

Formats the value using the given formatter.

impl Default for Metadata

fn default() -> Metadata

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Metadata

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Metadata

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
