Struct texlang::types::MathCode

pub struct MathCode(pub u16);

A math code.

The inner value is in the range [0, 32768).

See chapter 17 of the TeXBook for information on this type. The TeXBook presents an interpretation of the inner value. For example, the highest 3 bits represent the “class” of the math character. From Texlang’s perspective, however, a math character is just a regular integer and such interpretations are scoped to algorithms that consumes math characters.
