Type Alias Sign

pub(crate) type Sign = ri8<-1, 1>;

A type alias for the sign of a number.

It can be -1 for a negative sign, 1 for a positive sign or 0 for no sign.

Aliased Type

pub(crate) struct Sign {
    pub(crate) val: i8,
    pub(crate) min: i8,
    pub(crate) max: i8,
}

Fields

val: i8

The actual value of the integer.

Callers should not access this directly. There are some very rare cases where algorithms are too difficult to express on ranged integers, and it’s useful to be able to reach inside and access the raw value directly. (For example, the conversions between Unix epoch day and Gregorian date.)

min: i8

The minimum possible value computed so far.

This value is only present when debug_assertions are enabled. In that case, it is used to ensure the minimum possible value when the integer is actually observed (or converted) is still within the legal range.

Callers should not access this directly. There are some very rare cases where algorithms are too difficult to express on ranged integers, and it’s useful to be able to reach inside and access the raw value directly. (For example, the conversions between Unix epoch day and Gregorian date.)

max: i8

The maximum possible value computed so far.

This value is only present when debug_assertions are enabled. In that case, it is used to ensure the maximum possible value when the integer is actually observed (or converted) is still within the legal range.
