fn c_short_name_fmt(fmt: &mut Formatter) -> Result

A short-name description of the type, mainly used to fill "placeholders" such as when monomorphising generics structs or arrays.

fn c_define_self(definer: &mut dyn Definer) -> Result<()>

Necessary one-time code for CType::c_var() to make sense.

fn c_var_fmt(fmt: &mut Formatter, var_name: &str) -> Result

The core method of the trait: it provides the implementation to be used by CType::c_var, by bringing a Formatter in scope.

type OPAQUE_KIND = Concrete

fn c_short_name() -> ImplDisplay<Self>

Convenience function for callers / users of types implementing CType.

fn c_var(var_name: &str) -> ImplDisplay<Self>

Convenience function for callers / users of types implementing CType.
