Trait Integer 

pub(crate) trait Integer: Sized {
    const MAX_NUM_DIGITS: u8;
    const ZERO: Self;

    // Required methods
    fn push_digit(self, digit: u8) -> Self;
    fn checked_push_digit(self, digit: u8) -> Option<Self>;
}

Available on crate feature parsing only.

Marker trait for integer types.

Required Associated Constants

const MAX_NUM_DIGITS: u8

The maximum number of digits that this type can have.

const ZERO: Self

The zero value for this type.

Required Methods

fn push_digit(self, digit: u8) -> Self

Push a digit onto the end of this integer, assuming no overflow.

This is equivalent to self * 10 + digit.

fn checked_push_digit(self, digit: u8) -> Option<Self>

Push a digit onto the end of this integer, returning None on overflow.

This is equivalent to self.checked_mul(10)?.checked_add(digit).

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.
