Enum IntExt 

pub enum IntExt<Int = i32> {
    Int(Int),
    NegativeInf,
    PositiveInf,
}

An i32 or positive/negative infinity.

Notes on arithmetic operations:

• The result of the operation infty + -infty is undetermined, and if evaluated will cause a panic.
• Multiplying IntExt::PositiveInf or IntExt::NegativeInf with IntExt::I32(0) will yield IntExt::I32(0).

Variants

Int(Int)

NegativeInf

PositiveInf
