impl<'a> HashStable<StableHashingContext<'a>> for TyVid

pub fn hash_stable(
    &self,
    _hcx: &mut StableHashingContext<'a>,
    _hasher: &mut StableHasher
)

impl Ord for TyVid

pub fn cmp(&self, other: &TyVid) -> Ordering

This method returns an Ordering between self and other.

#[must_use]pub fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]pub fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]pub fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<TyVid> for TyVid

pub fn eq(&self, other: &TyVid) -> bool

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

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

This method tests for !=.

impl PartialOrd<TyVid> for TyVid

pub fn partial_cmp(&self, other: &TyVid) -> Option<Ordering>

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

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

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

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

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

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

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

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

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

impl StructuralEq for TyVid

impl StructuralPartialEq for TyVid

impl UnifyKey for TyVid

Raw TyVid are used as the unification key for sub_relations; they carry no values.

type Value = ()

pub fn index(&self) -> u32

pub fn from_index(i: u32) -> TyVid

pub fn tag() -> &'static str

pub 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.
