Extension trait adding convenience constructors for BigRational.

Required Methods

fn from_u64(value: u64) -> Self

Creates a BigRational from a u64 numerator with denominator 1.

fn from_frac_u64(numerator: u64, denominator: u64) -> Self

Creates a BigRational from a u64 numerator and denominator.

fn from_u128(value: u128) -> Self

Creates a BigRational from a u128 numerator with denominator 1.

fn from_frac_u128(numerator: u128, denominator: u128) -> Self

Creates a BigRational from a u128 numerator and denominator.

fn ceil_to_u128(&self) -> Option<u128>

Returns the ceiling of the rational value as u128, saturating and treating negative values as zero.

fn from_usize(value: usize) -> Self

Creates a BigRational from a usize numerator with denominator 1.

fn from_frac_usize(numerator: usize, denominator: usize) -> Self

Creates a BigRational from a usize numerator and denominator.

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.
