pub fn TODO() -> impl TexError + EndOfInputErrorExpand description
An error for work-in-progress Texlang code.
When working on Texlang code it’s often nice to figure out the logic first, and then go through later to polish the error cases. This function returns a “TODO” error that helps with this process.
Use the return value of this function in any place you plan to generate an error. Later on, follow Texlang best practices and create a specific error type for the case with a good error message.
