Enum RcPolicy 

pub enum RcPolicy {
    Standard,
    Deferred,
    AggressiveElision,
    Disabled,
}

Policy for how reference counting behaves.

Variants

Standard

Standard reference counting (increment on share, decrement on drop).

Deferred

Deferred reference counting (batch decrements at scope boundaries).

AggressiveElision

Aggressive elision (skip RC for provably linear values).

Disabled

No reference counting (for debugging, everything leaks).

Implementations

impl RcPolicy

pub fn is_deferred(&self) -> bool

Check if this policy uses deferred decrements.

pub fn allows_elision(&self) -> bool

Check if this policy allows elision.

pub fn is_enabled(&self) -> bool

Check if RC is enabled.

Trait Implementations

impl Clone for RcPolicy

fn clone(&self) -> RcPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RcPolicy

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

Formats the value using the given formatter.

impl Display for RcPolicy

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

Formats the value using the given formatter.

impl PartialEq for RcPolicy

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