Struct Closure 

pub struct Closure {
    pub params: Arc<[VarId]>,
    pub body: Arc<Core>,
    pub env: Arc<Env>,
    pub locals: u32,
}

Fields

params: Arc<[VarId]>

body: Arc<Core>

The same Arc the CoreKind::Lam node holds, so building a closure is a refcount bump rather than a copy of the code.

env: Arc<Env>

Behind an Arc so that calling the closure clones a pointer rather than the environment.

locals: u32

How many bindings the body makes, copied off the CoreKind::Lam node so that a call can size one frame for the parameters and all of them. crate::frames is what counts it.

Trait Implementations

impl Debug for Closure

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

Formats the value using the given formatter.

impl Ord for Closure

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Closure

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

Closures compare by identity of their code position. Two closures are never equal unless they came from the same lambda with the same captured frame, which is all any program should rely on.

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 Closure

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