Enum rustc_span::NonNarrowChar

source · [−]

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

Expand description

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

Variants

`ZeroWidth(BytePos)`

Represents a zero-width character.

`Wide(BytePos)`

Represents a wide (full-width) character.

`Tab(BytePos)`

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

Implementations

source

impl NonNarrowChar

source

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

source

pub fn pos(&self) -> BytePos

Returns the absolute offset of the character in the SourceMap.

source

pub fn width(&self) -> usize

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