Struct NoisyFloat

pub struct NoisyFloat<F: Float, C: FloatChecker<F>> { /* private fields */ }

A floating point number with a restricted set of legal values.

Typical users will not need to access this struct directly, but can instead use the type aliases found in the module noisy_float::types. However, this struct together with a FloatChecker implementation can be used to define custom behavior.

The underlying float type is F, usually f32 or f64. Valid values for the float are determined by the float checker C. If an invalid value would ever be returned from a method on this type, the method will panic instead, using either assert! or debug_assert! as defined by the float checker. The exception to this rule is for methods that return an Option containing a NoisyFloat, in which case the result would be None if the value is invalid.

Implementations

impl NoisyFloat<f32, NumChecker>

pub const fn unchecked_new(value: f32) -> Self

A const constructor that does not check whether value is valid.

WARNING: This constructor does not panic even in debug mode. As always, it is the user’s responsibility to ensure value is valid. Until Rust supports panics in const functions, this constructor is necessary to create a NoisyFloat in a const setting.

pub const fn const_raw(self) -> f32

A const function that returns the underlying float value.

impl NoisyFloat<f64, NumChecker>

pub const fn unchecked_new(value: f64) -> Self

A const constructor that does not check whether value is valid.

WARNING: This constructor does not panic even in debug mode. As always, it is the user’s responsibility to ensure value is valid. Until Rust supports panics in const functions, this constructor is necessary to create a NoisyFloat in a const setting.

pub const fn const_raw(self) -> f64

A const function that returns the underlying float value.

impl NoisyFloat<f32, FiniteChecker>

pub const fn unchecked_new(value: f32) -> Self
