Struct LambdaFn 

pub struct LambdaFn(pub Rc<dyn Fn(&[Value], Option<&mut IoContext>) -> Result<Value, String>>, pub String);

A compiled anonymous function closure with its source text.

The first field is the callable closure; the second is the display source (e.g. @(x) x^2) used by format_value and the who command.

Tuple Fields

0: Rc<dyn Fn(&[Value], Option<&mut IoContext>) -> Result<Value, String>>

1: String

Trait Implementations

impl Clone for LambdaFn

fn clone(&self) -> LambdaFn

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LambdaFn

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

Formats the value using the given formatter.

impl PartialEq for LambdaFn

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