Trait LogfBackend 

pub(crate) trait LogfBackend {
    const HAS_FMA: bool;

    // Required methods
    fn fmaf(&self, x: f32, y: f32, z: f32) -> f32;
    fn fma(&self, x: f64, y: f64, z: f64) -> f64;
    fn polyeval3(&self, x: f64, a0: f64, a1: f64, a2: f64) -> f64;
}

Required Associated Constants

const HAS_FMA: bool

Required Methods

fn fmaf(&self, x: f32, y: f32, z: f32) -> f32

fn fma(&self, x: f64, y: f64, z: f64) -> f64

fn polyeval3(&self, x: f64, a0: f64, a1: f64, a2: f64) -> f64

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.
