Trait LineStringTrait

pub trait LineStringTrait: Sized + GeometryTrait {
    type CoordType<'a>: 'a + CoordTrait<T = Self::T>
       where Self: 'a;

    // Required methods
    fn num_coords(&self) -> usize;

    // Provided methods
    fn coords(
        &self,

    fn coord(&self, i: usize) -> Option<Self::CoordType<'_>> { ... }
}

A trait for accessing data from a generic LineString.

A LineString is an ordered collection of two or more points, representing a path between locations.

Refer to geo_types::LineString for information about semantics and validity.

Required Associated Types

type CoordType<'a>: 'a + CoordTrait<T = Self::T> where Self: 'a

The type of each underlying coordinate, which implements CoordTrait

Required Methods

fn num_coords(&self) -> usize

The number of coordinates in this LineString

unsafe fn coord_unchecked(&self, i: usize) -> Self::CoordType<'_>

Access to a specified coordinate in this LineString

Safety

Accessing an index out of bounds is UB.

Provided Methods

fn coords( &self, ) -> impl DoubleEndedIterator + ExactSizeIterator<Item = Self::CoordType<'_>>

An iterator over the coordinates in this LineString

fn coord(&self, i: usize) -> Option<Self::CoordType<'_>>

Access to a specified coordinate in this LineString Will return None if the provided index is out of bounds

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
