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

Expand description

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

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

Implementations

source

impl Normal

source

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

Construct a new normal expression from the head and elements.

source

pub fn head(&self) -> &Expr

The head of this normal expression.

source

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.

source

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

The elements of this normal expression.

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

source

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

Returns true if the head of this expression is sym.
