pub struct BestFitting<'a, Context> { /* private fields */ }
Expand description

The first variant is the most flat, and the last is the most expanded variant. See best_fitting! macro for a more in-detail documentation

Implementations§

source§

impl<'a, Context> BestFitting<'a, Context>

source

pub unsafe fn from_arguments_unchecked(variants: Arguments<'a, Context>) -> Self

Creates a new best fitting IR with the given variants. The method itself isn’t unsafe but it is to discourage people from using it because the printer will panic if the slice doesn’t contain at least the least and most expanded variants.

You’re looking for a way to create a BestFitting object, use the best_fitting![least_expanded, most_expanded] macro.

§Safety

The slice must contain at least two variants.
