Enum Function

pub enum Function {
    Custom,
    Main(Expression),
}

Definition of a function.

All functions except for the main function are resolved during the creation of the AST.

Variants

Custom

A custom function.

A stub because the definition of the function was moved to its calls in the main function.

Main(Expression)

The main function.

An expression that takes no inputs (unit) and that produces no output (unit). The expression may panic midway through, signalling failure. Otherwise, the expression signals success.

This expression is evaluated when the program is run.

Trait Implementations

impl Clone for Function

fn clone(&self) -> Function

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Function

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

Formats the value using the given formatter.

impl Hash for Function

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 PartialEq for Function

fn eq(&self, other: &Function) -> 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 Eq for Function

impl StructuralPartialEq for Function
