Struct gpoint::GPoint

#[repr(transparent)]
pub struct GPoint<Float>(pub Float);

A wrapper around floats providing an implementation of Display which uses the underlying libc’s printf() with format "%g", for when you need to match exactly what C a program would output.

Float should be a floating point type, i.e. f32 or f64.

Available formatting options:

use gpoint::GPoint;

assert!(format!("{}",    GPoint(42f32))  == "42");
assert!(format!("{}",    GPoint(42f64))  == "42");
assert!(format!("{:.3}", GPoint(1.2345)) == "1.23");
assert!(format!("{:4}",  GPoint(42.))    == "  42");
assert!(format!("{:-4}", GPoint(42.))    == "42  ");
assert!(format!("{:04}", GPoint(42.))    == "0042");
assert!(format!("{:+}",  GPoint(42.))    == "+42");
assert!(format!("{:#4}", GPoint(42.))    == "42.0000");
