Formats the value using the given formatter.

impl<__D: Decoder> Decodable<__D> for FloatVid

fn decode(__decoder: &mut __D) -> Result<Self, <__D as Decoder>::Error>

impl<__E: Encoder> Encodable<__E> for FloatVid

impl Eq for FloatVid

impl Hash for FloatVid

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

pub fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher,

impl Ord for FloatVid

fn cmp(&self, other: &FloatVid) -> 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

Restrict a value to a certain interval.

impl PartialEq<FloatVid> for FloatVid

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

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

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

This method tests for !=.

impl PartialOrd<FloatVid> for FloatVid

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

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

#[must_use]pub fn lt(&self, other: &Rhs) -> bool

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

#[must_use]pub 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]pub fn gt(&self, other: &Rhs) -> bool

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

#[must_use]pub 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 StructuralEq for FloatVid

impl StructuralPartialEq for FloatVid

impl UnifyKey for FloatVid

type Value = Option<FloatVarValue>

fn index(&self) -> u32

fn from_index(i: u32) -> FloatVid

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.
