Struct Ref

pub struct Ref(/* private fields */);

A reference to an indirect object.

Implementations

impl Ref

pub const fn new(id: i32) -> Ref

Create a new indirect reference.

The provided value must be greater than zero.

Panics if id is out of the valid range.

pub const fn get(self) -> i32

Return the underlying number as a primitive type.

pub const fn next(self) -> Self

The next consecutive ID.

pub fn bump(&mut self) -> Self

Increase this ID by one and return the old one. Useful to turn this ID into a bump allocator of sorts.

Trait Implementations

impl Clone for Ref

fn clone(&self) -> Ref

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Ref

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

Formats the value using the given formatter.

impl Hash for Ref

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Ref

fn cmp(&self, other: &Ref) -> 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 Ref

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

impl PartialOrd for Ref

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

impl Primitive for Ref

fn write(self, buf: &mut Vec<u8>)

Write the object into a buffer.
