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

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

Performs the + operation.

impl Add for CharPos

type Output = CharPos

The resulting type after applying the + operator.

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

Performs the + operation.

impl AddAssign<usize> for CharPos

fn add_assign(&mut self, rhs: usize)

Performs the += operation.

impl AddAssign for CharPos

fn add_assign(&mut self, rhs: CharPos)

Performs the += operation.

impl Clone for CharPos

fn clone(&self) -> CharPos

Returns a duplicate 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<(), Error>

Formats the value using the given formatter.

impl Hash for CharPos

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 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.

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

Performs the - operation.

impl Sub for CharPos

type Output = CharPos

The resulting type after applying the - operator.

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

Performs the - operation.

impl SubAssign<usize> for CharPos

fn sub_assign(&mut self, rhs: usize)

Performs the -= operation.

impl SubAssign for CharPos

fn sub_assign(&mut self, rhs: CharPos)

Performs the -= operation.
