Expand description

Compile-time type information.

## Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

§

### Float(Float)

🔬This is a nightly-only experimental API. (`type_info` #146922)
