Struct StickyRc 

pub struct StickyRc { /* private fields */ }

A reference counter that saturates at MAX (immortal objects).

Implementations

impl StickyRc

pub fn new(initial: u32, max: u32) -> Self

Create a counter with initial count and given max.

pub fn inc(&mut self)

Increment (saturates at max).

pub fn dec(&mut self) -> bool

Decrement (saturates at 0). Returns true if now zero.

pub fn is_immortal(&self) -> bool

Whether at max (immortal).

pub fn count(&self) -> u32

Current count.

pub fn is_zero(&self) -> bool

Whether the count is zero.

Trait Implementations

impl Clone for StickyRc

fn clone(&self) -> StickyRc

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StickyRc

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

Formats the value using the given formatter.

impl Default for StickyRc

fn default() -> Self

Returns the “default value” for a type.

impl Display for StickyRc

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

Formats the value using the given formatter.

impl PartialEq for StickyRc

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