Struct CharIndex 

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

A position in the character list (TextPage::chars) — the sequence a --txt dump emits.

Distinct from TextIndex on purpose: the two sequences disagree. A control character or an unmapped code is in this one and not the other, and one character here can become several there. The compiler is asked to notice instead of the caller.

Implementations

impl CharIndex

pub const fn new(index: usize) -> Self

The character-list position at this position.

pub const fn get(self) -> usize

The position as a plain number.

Trait Implementations

impl Ord for CharIndex

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

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 CharIndex

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for CharIndex

fn partial_cmp(&self, other: &CharIndex) -> 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
