Struct wolfram_expr::Normal

pub struct Normal<E = Expr> { /* private fields */ }

Wolfram Language “normal” expression: f[...].

A normal expression is any expression that consists of a head and zero or more arguments.

Implementations

impl Normal

pub fn new<E: Into<Expr>>(head: E, contents: Vec<Expr>) -> Self

Construct a new normal expression from the head and elements.

pub fn head(&self) -> &Expr

The head of this normal expression.

pub fn elements(&self) -> &[Expr]

The elements of this normal expression.

If head conceptually represents a function, these are the arguments that are being applied to head.

pub fn into_elements(self) -> Vec<Expr>

The elements of this normal expression.

Use Normal::elements() to get a reference to this value.

pub fn has_head(&self, sym: &Symbol) -> bool

Returns true if the head of this expression is sym.

Trait Implementations

impl<E: Clone> Clone for Normal<E>

fn clone(&self) -> Normal<E>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<E: Debug> Debug for Normal<E>

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

Formats the value using the given formatter.

impl Display for Normal

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

Formats the value using the given formatter.

impl From<Normal<Expr>> for Expr

fn from(normal: Normal) -> Expr

Converts to this type from the input type.

impl<E: Hash> Hash for Normal<E>

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

Feeds this value into the given Hasher.

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

Feeds a slice of this type into the given Hasher.

impl<E: PartialEq> PartialEq<Normal<E>> for Normal<E>

fn eq(&self, other: &Normal<E>) -> 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.
