Struct Glyph 

pub(crate) struct Glyph {
    pub(crate) shape: GlyphShape,
    pub(crate) name: &'static str,
    pub(crate) normal: Option<char>,
    pub(crate) superscript: Option<char>,
    pub(crate) subscript: Option<char>,
    pub(crate) advance: bool,
}

A character which might appear in source code.

We include mappings to Unicode representation where this exists. However, there are also cases where more than one Unicode character (in the assembler input) might get mapped to the same Glyph; see canonicalise_char.

Fields

shape: GlyphShape

Indicates the shape of the glyph without regard to its (superscript/subscript/normal) position with respect to the character baseline.

name: &'static str

The name of the glyph as we would use it inside @...@.

normal: Option<char>

The Unicode representation of this glyph when in normal script.

superscript: Option<char>

The Unicode representation of this glyph when in superscript.

subscript: Option<char>

The Unicode representation of this glyph when in subscript.

advance: bool

When advance is false, this glyph does not advance the Lincoln Writer’s print carriage. This appears to be true for character codes 0o12 (underbar, overbar) and 0o13 (circle, square). We should provide a reference for this, but just now I’m taking this info from the code in base/src/charset.rs which deals with these character codes.

We try to use combining characters for these.

Implementations

impl Glyph

pub(crate) fn shape(&self) -> GlyphShape

pub(crate) fn get_char(&self, script: Script) -> Option<char>

Trait Implementations

impl Debug for Glyph

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

Formats the value using the given formatter.

impl PartialEq for Glyph

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