Enum rustc_ap_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.

Wide(BytePos)

Represents a wide (full-width) character.

Tab(BytePos)

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

Methods

impl NonNarrowChar

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).
