Struct MinimumBoundingRectangle 

pub struct MinimumBoundingRectangle {
    pub min_x: f64,
    pub min_y: f64,
    pub max_x: f64,
    pub max_y: f64,
}

Parsed Minimum Bounding Rectangle from an R-tree record.

Examples

use idb::innodb::rtree::MinimumBoundingRectangle;
use byteorder::{BigEndian, ByteOrder};

let mut buf = vec![0u8; 32];
BigEndian::write_f64(&mut buf[0..], 1.0);
BigEndian::write_f64(&mut buf[8..], 2.0);
BigEndian::write_f64(&mut buf[16..], 3.0);
BigEndian::write_f64(&mut buf[24..], 4.0);

let mbr = MinimumBoundingRectangle::parse(&buf).unwrap();
assert_eq!(mbr.min_x, 1.0);
assert_eq!(mbr.min_y, 2.0);
assert_eq!(mbr.max_x, 3.0);
assert_eq!(mbr.max_y, 4.0);
