Struct syntax_pos::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 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 PartialOrd<CharPos> 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: &CharPos) -> bool

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

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

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

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

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

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

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

impl Copy for CharPos

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 !=.

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 Ord for CharPos

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

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Returns max if self is greater than max, and min if self is less than min. Otherwise this will return self. Panics if min > max.

impl Eq for CharPos

impl Debug for CharPos

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

Formats the value using the given formatter.

impl Sub<CharPos> for CharPos

type Output = CharPos

The resulting type after applying the - operator.

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

Performs the - operation.

impl Hash for CharPos

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

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given [Hasher].

impl Add<CharPos> for CharPos

type Output = CharPos

The resulting type after applying the + operator.

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

Performs the + operation.
