Struct IdU8 

pub struct IdU8<T> { /* private fields */ }

A struct representing IDs usable for various purposes using an eight bit wide unsigned integer.

Please see the Id type for more general information and usage examples.

Implementations

impl<T> IdU8<T>

pub unsafe fn new_unchecked(id: u8) -> Self

Create a new ID using the given value.

Panics

This constructor panics if an overflow of the underlying counter occurred.

Safety

• id must not be zero
• id should be unique with respect to other IDs created for this T to preserve the invariant that IDs are unique

pub fn new() -> Self

Create a new unique ID.

Panics

This constructor panics if an overflow of the underlying counter occurred.

pub fn get(self) -> u8

Retrieve the underlying integer value.

Trait Implementations

impl<T: Clone> Clone for IdU8<T>

fn clone(&self) -> IdU8<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T> Debug for IdU8<T>

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

Formats the value using the given formatter.

impl<T> Default for IdU8<T>

fn default() -> Self

Create a new unique ID.

impl<T> Display for IdU8<T>

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

Format the ID with the given formatter.

impl<T: Hash> Hash for IdU8<T>

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<T: Ord> Ord for IdU8<T>

fn cmp(&self, other: &IdU8<T>) -> 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<T: PartialEq> PartialEq for IdU8<T>

fn eq(&self, other: &IdU8<T>) -> 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<T: PartialOrd> PartialOrd for IdU8<T>

fn partial_cmp(&self, other: &IdU8<T>) -> 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.
