Enum rustc_span::NonNarrowChar

pub enum NonNarrowChar {
    ZeroWidth(RelativeBytePos),
    Wide(RelativeBytePos),
    Tab(RelativeBytePos),
}

Identifies an offset of a non-narrow character in a SourceFile.

Variants

ZeroWidth(RelativeBytePos)

Represents a zero-width character.

Wide(RelativeBytePos)

Represents a wide (full-width) character.

Tab(RelativeBytePos)

Represents a tab character, represented visually with a width of 4 characters.

Implementations

impl NonNarrowChar

pub(crate) fn new(pos: RelativeBytePos, width: usize) -> Self

pub fn pos(&self) -> RelativeBytePos

Returns the relative offset of the character in the SourceFile.

pub fn width(&self) -> usize

Returns the width of the character, 0 (zero-width) or 2 (wide).

Trait Implementations

impl Add<RelativeBytePos> for NonNarrowChar

type Output = NonNarrowChar

The resulting type after applying the + operator.

fn add(self, rhs: RelativeBytePos) -> Self

Performs the + operation.

impl Clone for NonNarrowChar

fn clone(&self) -> NonNarrowChar

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NonNarrowChar

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

Formats the value using the given formatter.

impl<__D: Decoder> Decodable<__D> for NonNarrowChar

fn decode(__decoder: &mut __D) -> Self

impl<__E: Encoder> Encodable<__E> for NonNarrowChar

fn encode(&self, __encoder: &mut __E)

impl<__CTX> HashStable<__CTX> for NonNarrowCharwhere __CTX: HashStableContext,

fn hash_stable(&self, __hcx: &mut __CTX, __hasher: &mut StableHasher)

impl PartialEq<NonNarrowChar> for NonNarrowChar

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Sub<RelativeBytePos> for NonNarrowChar

type Output = NonNarrowChar

The resulting type after applying the - operator.

fn sub(self, rhs: RelativeBytePos) -> Self

Performs the - operation.

impl Copy for NonNarrowChar

impl Eq for NonNarrowChar

impl StructuralEq for NonNarrowChar

impl StructuralPartialEq for NonNarrowChar

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
