impl<L: Language, N: Analysis<L>> Index<Id> for EGraph<L, N>

Given an Id using the egraph[id] syntax, retrieve the e-class.

type Output = EClass<L, <N as Analysis<L>>::Data>

The returned type after indexing.

fn index(&self, id: Id) -> &Self::Output

Performs the indexing (container[index]) operation.

impl<L: Language> Index<Id> for RecExpr<L>

type Output = L

The returned type after indexing.

fn index(&self, id: Id) -> &L

Performs the indexing (container[index]) operation.

impl<L: Language, N: Analysis<L>> IndexMut<Id> for EGraph<L, N>

Given an Id using the &mut egraph[id] syntax, retrieve a mutable reference to the e-class.

fn index_mut(&mut self, id: Id) -> &mut Self::Output

Performs the mutable indexing (container[index]) operation.

impl<L: Language> IndexMut<Id> for RecExpr<L>

fn index_mut(&mut self, id: Id) -> &mut L

Performs the mutable indexing (container[index]) operation.

impl LanguageChildren for Id

fn len(&self) -> usize

Returns the number of children.

fn can_be_length(n: usize) -> bool

Checks if n is an acceptable number of children for this type.

fn from_vec(v: Vec<Id>) -> Self

Create an instance of this type from a Vec<Id>, with the guarantee that can_be_length is already true on the Vec.

fn as_slice(&self) -> &[Id]

Returns a slice of the children Ids.

fn as_mut_slice(&mut self) -> &mut [Id]

Returns a mutable slice of the children Ids.

fn is_empty(&self) -> bool

Checks if there are no children.

impl Ord for Id

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<Id> for Id

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

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

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

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

impl PartialOrd<Id> for Id

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

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

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

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

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

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

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

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

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 Serialize for Id

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.
