Enum SpecialWidthChar

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

Identifies the position of a special width character in a Source. Special width in this context means a character with byte width != 1.

Variants

ZeroWidth(BytePos)

A zero width character. These are mostly ASCII control characters.

Wide(BytePos)

A full width char.

Tab(BytePos)

Tab byte \t/0x09

Implementations

impl SpecialWidthChar

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

Tries to create a new SpecialWidthChar. The kind is derived from the given width.

Panics

Panics if width can not be mapped to a SpecialWidthChar.

pub const fn width(&self) -> usize

Returns the width in bytes of the character.

pub const fn pos(&self) -> &BytePos

Returns the position of the character.

Trait Implementations

impl Clone for SpecialWidthChar

fn clone(&self) -> SpecialWidthChar

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SpecialWidthChar

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

Formats the value using the given formatter.

impl Hash for SpecialWidthChar

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, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SpecialWidthChar

fn eq(&self, other: &SpecialWidthChar) -> 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.
