Enum rustc_span::NonNarrowChar

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

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

Variants

ZeroWidth(BytePos)

Represents a zero-width character.

Tuple Fields of ZeroWidth

0: BytePos

Wide(BytePos)

Represents a wide (full-width) character.

Tuple Fields of Wide

0: BytePos

Tab(BytePos)

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

Tuple Fields of Tab

0: BytePos

Implementations

impl NonNarrowChar

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

pub fn pos(&self) -> BytePos

Returns the absolute offset of the character in the SourceMap.

pub fn width(&self) -> usize

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

Trait Implementations

impl Add<BytePos> for NonNarrowChar

type Output = Self

The resulting type after applying the + operator.

fn add(self, rhs: BytePos) -> 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.

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.
