Trait Rounding 

pub trait Rounding: Copy + Default {
    type MaximumError: From<Infallible> + Into<Error> + Error;
}

Rounding mode

Implementations of this trait are (probably) unit structs, used to mark the type of rounding used at the type level.

Implied implementations

impl<S, T: ConvExact<S>> ConvTo<S, R> is is implemented for each rounding mode R provided by this crate since a more general impl over R: Rounding is not compatible with the wider trait design under the limitations of Rust’s current trait solver. Any rounding mode added by a third-party crate should therefore provide a similar impl.

Required Associated Types

type MaximumError: From<Infallible> + Into<Error> + Error

Maximum error type

Dyn Compatibility

This trait is not dyn compatible.

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