Implementations

impl NativeFunction

pub fn new( function: fn(Span, &[Spanned<Value>]) -> Result<Spanned<Value>, EvalError>, ) -> Self

pub fn call( &self, span: Span, args: &[Spanned<Value>], ) -> Result<Spanned<Value>, EvalError>

Trait Implementations

impl Clone for NativeFunction

fn clone(&self) -> NativeFunction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NativeFunction

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

Formats the value using the given formatter.

impl PartialEq for NativeFunction

fn eq(&self, other: &NativeFunction) -> 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 PartialOrd for NativeFunction

fn partial_cmp(&self, other: &NativeFunction) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
