Struct NatRangeIndex 

pub struct NatRangeIndex { /* private fields */ }

Typed identity for a concrete compiler-generated Nat range index.

The core carries this non-zero size directly; display names are derived only for diagnostics and compatibility with APIs that still need an IndexName.

Implementations

impl NatRangeIndex

pub const fn new(size: NonZeroUsize) -> Self

Create an identity for a non-empty Nat range index.

pub fn try_from_u64(size: u64) -> Result<Self, NatRangeIndexError>

Try to create an identity from an AST/runtime u64 size.

Errors

Returns an error when size is zero or cannot fit in usize on this target.

pub const fn size(self) -> NonZeroUsize

Return the non-zero in-memory size.

pub fn size_u64(self) -> u64

Return the size as a u64 for Nat-expression comparisons and display.

pub fn display_name(self) -> IndexName

Render this identity for diagnostics as source-level range(N) syntax.

Trait Implementations

impl Clone for NatRangeIndex

fn clone(&self) -> NatRangeIndex

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for NatRangeIndex

impl Debug for NatRangeIndex

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

Formats the value using the given formatter.

impl Eq for NatRangeIndex

impl Hash for NatRangeIndex

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 NatRangeIndex

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

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

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