Struct Tree 

pub struct Tree(pub Vec<Expression>);

A collection of expressions which may recursively form an expression tree

Seperate struct, use mutual recursion between tree and expressions to make parsing easier to implement. May combine them in the future.

Tuple Fields

0: Vec<Expression>

Implementations

impl Tree

pub fn new() -> Tree

Create an empty tree

Trait Implementations

impl Clone for Tree

fn clone(&self) -> Tree

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Tree

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

Formats the value using the given formatter.

impl Default for Tree

fn default() -> Self

Returns the “default value” for a type.

impl Display for Tree

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

Formats the value using the given formatter.

impl Eq for Tree

impl PartialEq for Tree

fn eq(&self, other: &Tree) -> 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.
