Struct Closure 

pub struct Closure {
    pub function_id: u16,
    pub captured_env: CapturedEnvironment,
}

A closure captures a function definition along with its environment

Fields

function_id: u16

The function ID (bytecode index)

captured_env: CapturedEnvironment

Captured environment (variable bindings from enclosing scope)

Trait Implementations

impl Clone for Closure

fn clone(&self) -> Closure

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Closure

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

Formats the value using the given formatter.

impl PartialEq for Closure

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.
