Struct CharPos

pub struct CharPos(pub usize);

A character offset.

Because of multibyte UTF-8 characters, a byte offset is not equivalent to a character offset. The [SourceMap] will convert BytePos values to CharPos values as necessary.

Tuple Fields

0: usize

Trait Implementations

impl Add for CharPos

type Output = CharPos

The resulting type after applying the + operator.

fn add(self, rhs: CharPos) -> CharPos

Performs the + operation.

impl Clone for CharPos

fn clone(&self) -> CharPos

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CharPos

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

Formats the value using the given formatter.

impl Ord for CharPos

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

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

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

impl Pos for CharPos

fn from_usize(n: usize) -> CharPos

fn to_usize(&self) -> usize

fn from_u32(n: u32) -> CharPos

fn to_u32(&self) -> u32

impl Sub for CharPos

type Output = CharPos

The resulting type after applying the - operator.

fn sub(self, rhs: CharPos) -> CharPos

Performs the - operation.

impl Copy for CharPos

impl Eq for CharPos

impl StructuralPartialEq for CharPos
