Trait MachineConstants 

pub trait MachineConstants: Float + Debug {
    // Required methods
    fn machine_epsilon() -> Self;
    fn min_positive_normal() -> Self;
    fn max_finite() -> Self;
    fn min_positive_subnormal() -> Self;
    fn mantissa_digits() -> u32;

    // Provided method
    fn radix() -> u32 { ... }
}

Machine-specific constants for a floating-point type.

Provides type-level access to epsilon, minimum/maximum normal values, minimum positive subnormal, and radix information.

Required Methods

fn machine_epsilon() -> Self

Machine epsilon (difference between 1.0 and the next representable value).

fn min_positive_normal() -> Self

Smallest positive normal number.

fn max_finite() -> Self

Largest finite number.

fn min_positive_subnormal() -> Self

Smallest positive subnormal number (closest to zero without being zero).

fn mantissa_digits() -> u32

Number of significand (mantissa) bits.

Provided Methods

fn radix() -> u32

Radix of the floating-point representation (always 2 for IEEE 754).

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.
