    hcx: &mut StableHashingContext<'a>,
    hasher: &mut StableHasher
)

impl<'tcx> Ord for ConstVid<'tcx>

fn cmp(&self, other: &ConstVid<'tcx>) -> Ordering

This method returns an Ordering between self and other.

#[must_use]

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

Compares and returns the maximum of two values.

#[must_use]

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

Compares and returns the minimum of two values.

#[must_use]

fn clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval.

impl<'tcx> PartialEq<ConstVid<'tcx>> for ConstVid<'tcx>

fn eq(&self, other: &ConstVid<'tcx>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &ConstVid<'tcx>) -> bool

This method tests for !=.

impl<'tcx> PartialOrd<ConstVid<'tcx>> for ConstVid<'tcx>

fn partial_cmp(&self, other: &ConstVid<'tcx>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

#[must_use]

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

This method tests less than (for self and other) and is used by the < operator.

#[must_use]

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

#[must_use]

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

This method tests greater than (for self and other) and is used by the > operator.

#[must_use]

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl<'tcx> UnifyKey for ConstVid<'tcx>

type Value = ConstVarValue<'tcx>

fn index(&self) -> u32

fn from_index(i: u32) -> Self

fn tag() -> &'static str

fn order_roots(
    a: Self,
    a_value: &Self::Value,
    b: Self,
    b_value: &Self::Value
) -> Option<(Self, Self)>

If true, then self should be preferred as root to other. Note that we assume a consistent partial ordering, so returning true implies that other.prefer_as_root_to(self) would return false. If there is no ordering between two keys (i.e., a.prefer_as_root_to(b) and b.prefer_as_root_to(a) both return false) then the rank will be used to determine the root in an optimal way.
