pub fn total_cmp(&self, other: &f32) -> Ordering[src]

🔬 This is a nightly-only experimental API. (total_cmp)

Returns an ordering between self and other values. Unlike the standard partial comparison between floating point numbers, this comparison always produces an ordering in accordance to the totalOrder predicate as defined in IEEE 754 (2008 revision) floating point standard. The values are ordered in following order:

  • Negative quiet NaN
  • Negative signaling NaN
  • Negative infinity
  • Negative numbers
  • Negative subnormal numbers
  • Negative zero
  • Positive zero
  • Positive subnormal numbers
  • Positive numbers
  • Positive infinity
  • Positive signaling NaN
  • Positive quiet NaN

Note that this function does not always agree with the PartialOrd and PartialEq implementations of f32. In particular, they regard negative and positive zero as equal, while total_cmp doesn’t.

Example

#![feature(total_cmp)]
struct GoodBoy {
    name: String,
    weight: f32,
}

let mut bois = vec![
    GoodBoy { name: "Pucci".to_owned(), weight: 0.1 },
    GoodBoy { name: "Woofer".to_owned(), weight: 99.0 },
    GoodBoy { name: "Yapper".to_owned(), weight: 10.0 },
    GoodBoy { name: "Chonk".to_owned(), weight: f32::INFINITY },
    GoodBoy { name: "Abs. Unit".to_owned(), weight: f32::NAN },
    GoodBoy { name: "Floaty".to_owned(), weight: -5.0 },
];

bois.sort_by(|a, b| a.weight.total_cmp(&b.weight));
