const REPORT: &'static TypeReport

A compile-time generated report of the fields of the type, allowing for compatibility inspection.

const ID: u64

A stable (and ideally unique) identifier for the type. Often generated using crate::report::gen_id, but can be manually set.

impl<T0: Ord, T1: Ord, T2: Ord, T3: Ord> Ord for Tuple4<T0, T1, T2, T3>

fn cmp(&self, other: &Tuple4<T0, T1, T2, T3>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
