Struct roaring_landmask::mask::RoaringMask

pub struct RoaringMask { /* private fields */ }

Implementations

impl RoaringMask

pub fn from_compressed<P: AsRef<Path>>(path: P) -> Result<Self>

impl RoaringMask

pub fn new() -> Result<Self>

Make a new mask.

pub fn dx(&self) -> f64

pub fn dy(&self) -> f64

pub fn contains(&self, x: f64, y: f64) -> bool

Check if point (x, y) is on land.

x is longitude, [-180, 180] east y is latitude, [- 90, 90] north

The check is optimistic, it will yield true for points that are closer to the shore than the resolution of the landmask. The positive points should be checked against the vectorized land shapes.

Returns true if the point is on land or close to the shore.

pub fn contains_many(
    &self,
    py: Python<'_>,
    x: PyReadonlyArrayDyn<'_, f64>,
    y: PyReadonlyArrayDyn<'_, f64>
) -> Py<PyArray<bool, Ix1>>

pub fn contains_many_par(
    &self,
    py: Python<'_>,
    x: PyReadonlyArrayDyn<'_, f64>,
    y: PyReadonlyArrayDyn<'_, f64>
) -> Py<PyArray<bool, IxDyn>>

Trait Implementations

impl Clone for RoaringMask

fn clone(&self) -> RoaringMask

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RoaringMask

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

Formats the value using the given formatter.

impl Default for RoaringMask

fn default() -> RoaringMask

Returns the “default value” for a type.

impl IntoPy<Py<PyAny>> for RoaringMask

fn into_py(self, py: Python<'_>) -> PyObject

Performs the conversion.

impl PyClass for RoaringMask

type Dict = PyClassDummySlot

Specify this class has #[pyclass(dict)] or not.

type WeakRef = PyClassDummySlot

Specify this class has #[pyclass(weakref)] or not.

type BaseNativeType = PyAny

The closest native ancestor. This is PyAny by default, and when you declare #[pyclass(extends=PyDict)], it’s PyDict.

impl PyClassImpl for RoaringMask

const DOC: &'static str

Class doc string

const IS_BASETYPE: bool

#[pyclass(subclass)]

const IS_SUBCLASS: bool

#[pyclass(extends=…)]

type Layout = PyCell<Self>

Layout

type BaseType = PyAny

Base class

type ThreadChecker = ThreadCheckerStub<RoaringMask>

This handles following two situations:

fn for_all_items(visitor: &mut dyn FnMut(&PyClassItems))

fn dict_offset() -> Option<isize>

fn weaklist_offset() -> Option<isize>

impl PyMethods<RoaringMask> for PyClassImplCollector<RoaringMask>

fn py_methods(self) -> &'static PyClassItems

impl PyTypeInfo for RoaringMask

type AsRefTarget = PyCell<Self>

Utility type to make Py::as_ref work.

const NAME: &'static str

Class name.

const MODULE: Option<&'static str>

Module name, if any.

fn type_object_raw(py: Python<'_>) -> *mut PyTypeObject

PyTypeObject instance for this type.

fn is_type_of(object: &PyAny) -> bool

Checks if object is an instance of this type or a subclass of this type.

fn is_exact_type_of(object: &PyAny) -> bool

Checks if object is an instance of this type.
