Struct ItemId 

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

A source unit item ID. Only used in SourceUnit.

Implementations

impl ItemId

pub const MAX: ItemId

The maximum index value.

pub const fn new(value: u32) -> ItemId

Creates a new ItemId from the given value.

Panics

Panics if value exceeds MAX.

pub const unsafe fn new_unchecked(value: u32) -> ItemId

Creates a new ItemId from the given value.

Safety

The caller must ensure that value is less than or equal to MAX.

pub const fn try_new(value: u32) -> Option<ItemId>

Creates a new ItemId from the given value.

Returns None if value exceeds MAX.

pub const fn from_usize(value: usize) -> ItemId

Creates a new ItemId from the given value.

Panics

Panics if value exceeds MAX.

pub const unsafe fn from_usize_unchecked(value: usize) -> ItemId

Creates a new ItemId from the given value.

Safety

The caller must ensure that value is less than or equal to MAX.

pub const fn try_from_usize(value: usize) -> Option<ItemId>

Creates a new ItemId from the given value.

Returns None if value exceeds MAX.

pub const fn get(self) -> u32

Returns the underlying index value.

pub const fn index(self) -> usize

Returns the underlying index value.

Trait Implementations

impl Clone for ItemId

fn clone(&self) -> ItemId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ItemId

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

Formats the value using the given formatter.

impl Hash for ItemId

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

where __H: Hasher,

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 Idx for ItemId

fn from_usize(value: usize) -> ItemId

Construct an Index from a usize. This is equivalent to From<usize>.

fn index(self) -> usize

Get the underlying index. This is equivalent to Into<usize>

impl Ord for ItemId

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

fn eq(&self, other: &ItemId) -> 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 ItemId

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