Trait Error 

pub trait Error {
    // Required methods
    fn erf(self) -> Self;
    fn erfc(self) -> Self;
    fn erfinv(self) -> Self;
    fn erfcinv(self) -> Self;
}

Provides error, also called the Gauss error function related functions

Required Methods

fn erf(self) -> Self

Error function

\operatorname{erf}(z) = \frac{2}{\sqrt\pi}\int_0^z e^{-t^2}\,dt.

For more information

Arguments

self:

fn erfc(self) -> Self

Complementary error function

\operatorname{erfc}(z) = 1 - \operatorname{erf}(z),

Arguments

self

fn erfinv(self) -> Self

Inverse error function

\operatorname{erfinv}(x) = \operatorname{erf}^{-1}(x) \quad \text{for} \quad x \in (-1, 1)

For more information

Arguments

-1.0 < x < 1.0

Panics

if x < -1.0 or x > 1.0

fn erfcinv(self) -> Self

Inverse complementary error function

\operatorname{erfc}^{-1}(1-z) = \operatorname{erf}^{-1}(z)

Arguments

0 <= x <= 2.0

Panics

if x < 0.0 or x > 2.0

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
