Struct ByteIndex

pub(crate) struct ByteIndex(usize);

A read-only text index in bytes.

Guarantee to be on a char boundary and in text bounds.

Tuple Fields

0: usize

Implementations

impl ByteIndex

fn new(i: usize) -> Self

pub(crate) fn value(&self) -> usize

pub(crate) fn code_point_at(&self, text: &str) -> usize

Converts byte position into a code point position.

pub(crate) fn char_from(&self, text: &str) -> char

Converts byte position into a character.

Trait Implementations

impl Clone for ByteIndex

fn clone(&self) -> ByteIndex

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ByteIndex

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

Formats the value using the given formatter.

impl PartialEq for ByteIndex

fn eq(&self, other: &ByteIndex) -> 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.
