Struct rustc_ap_rustc_span::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.

Trait Implementations

impl Add<CharPos> for CharPos

type Output = CharPos

The resulting type after applying the + operator.

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

impl Eq for CharPos

impl Ord for CharPos

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

This method returns an Ordering between self and other.

#[must_use]pub fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]pub fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

Restrict a value to a certain interval.

impl PartialEq<CharPos> for CharPos

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

fn partial_cmp(&self, other: &CharPos) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

#[must_use]pub fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

#[must_use]pub fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

#[must_use]pub fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

#[must_use]pub fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
