Struct User 

pub struct User {
    pub index: usize,
    pub captures: HashSet<usize>,
    pub environment: HashMap<usize, Value>,
}

A user-defined function.

Fields

index: usize

The index of the function’s chunk.

TODO: comparing index is not enough to compare two functions

captures: HashSet<usize>

The variables captured by the function from the environment.

This is determined at compile time.

environment: HashMap<usize, Value>

The values of the variables in the function’s environment at the time of the function’s creation.

This is determined at runtime.

Implementations

impl User

pub fn new(index: usize, captures: HashSet<usize>) -> Self

Creates a new user-defined function with the given chunk index an captured variables.

Trait Implementations

impl Clone for User

fn clone(&self) -> User

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for User

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

Formats the value using the given formatter.

impl PartialEq for User

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