Enum Node 

pub enum Node {
    Element(u16, String),
    Group(u16, Vec<Node>),
    ForumulaUnit(u16, Vec<Node>),
    Reactants(Vec<Node>),
    Products(Vec<Node>),
    Equation(Box<Node>, Box<Node>),
}

A Node in the AST (abstract syntax tree)

Variants

Element(u16, String)

Chemical elements e.g. O2. The number is the subscript, in this case 2

Group(u16, Vec<Node>)

Groups of elements or other groups (Polyatoms) e.g. (2FeO2)4 The number is the subscript, in this case 4

ForumulaUnit(u16, Vec<Node>)

Forumula Unit, a few elements and/or polyatoms eg 7(NH4)2SO4 This number is the coeffecient, in this case 7

Reactants(Vec<Node>)

The reactants side (left) of yields (->)

Products(Vec<Node>)

The products side (right) of yeilds (->)

Equation(Box<Node>, Box<Node>)

The whole equation

Trait Implementations

impl Debug for Node

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Node

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

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.

impl StructuralPartialEq for Node
