Enum Plan 

pub enum Plan {
    Chain,
    Frame(IdRange<CaptureId>),
}

How a closure captures its environment.

Variants

Chain

Share the defining environment by reference. Used when the closure is applied where it is made (a direct application, a builtin’s thunk argument), avoiding frame allocation.

Frame(IdRange<CaptureId>)

Copy the free variables into a fresh frame, the default for escaping closures. An empty plan is a closed lambda.

Trait Implementations

impl Clone for Plan

fn clone(&self) -> Plan

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Plan

impl Debug for Plan

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

Formats the value using the given formatter.

impl Eq for Plan

impl PartialEq for Plan

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