Struct ArenaIdx 

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

Index into crate::model::ParsedTree::arena (the child-node store) — a crate::model::Tree::children_start. NOT a length: children_len is a plain count, not an index into any space, so it stays a bare u32/usize.

Implementations

impl ArenaIdx

pub fn index(self) -> usize

The underlying index as a usize.

Trait Implementations

impl Clone for ArenaIdx

fn clone(&self) -> ArenaIdx

Returns a duplicate of the value.

impl Ord for ArenaIdx

fn cmp(&self, other: &ArenaIdx) -> 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.

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for ArenaIdx

fn eq(&self, other: &ArenaIdx) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl PartialOrd for ArenaIdx

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