crs: Crs

Implementations

impl Schema

pub fn new(fields: Vec<FieldDef>, geometry: Option<GeomField>, crs: Crs) -> Self

pub fn field(&self, idx: usize) -> Option<&FieldDef>

pub fn field_index(&self, name: &str) -> Option<usize>

pub fn field_by_name(&self, name: &str) -> Option<&FieldDef>

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn validate_row(&self, values: &[Value]) -> Result<()>

Validate that an attribute row has the right arity and each value’s type tag matches the schema (nulls pass for nullable fields).

Trait Implementations

impl Clone for Schema

fn clone(&self) -> Schema

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Schema

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

Formats the value using the given formatter.

impl PartialEq for Schema

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
