Function buffer_point 

pub fn buffer_point(point: &Point, distance: f64, resolution: usize) -> Polygon

This function returns the buffered n-gon of the given point.

Arguments

• point: Point to buffer.
• distance: determines the distance from the original point to each edge of the resulting n-gon.
• resolution: how many sides the resulting polygon will have (n of n-gon).

Example

use geo_buf::buffer_point;
use geo::{Point, Polygon, HasDimensions};

let p1 = Point::new(0.,0.);
let buffered = buffer_point(&p1, 1., 12);

let neg_empty = buffer_point(&p1, -1., 12);
assert!(neg_empty.is_empty())
