Trait Round 

pub trait Round
where
    Self: Sized,
{
    // Required methods
    fn round(self, n_frac_digits: i8) -> Self;
    fn checked_round(self, n_frac_digits: i8) -> Option<Self>;
}

Types providing methods to round their values to a given number of fractional digits.

Required Methods

fn round(self, n_frac_digits: i8) -> Self

Returns a new Self instance with its value rounded to n_frac_digits fractional digits according to the current RoundingMode.

fn checked_round(self, n_frac_digits: i8) -> Option<Self>

Returns a new Self instance with its value rounded to n_frac_digits fractional digits according to the current RoundingMode, wrapped in Option::Some, or Option::None if the result can not be represented by Self.

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.
