### FailedToUnescape(EscapeError)

🔬This is a nightly-only experimental API. (`proc_macro_value` #136652)

The literal failed to be escaped, take a look at `EscapeError` for more information.

### InvalidLiteralKind

🔬This is a nightly-only experimental API. (`proc_macro_value` #136652)

Trying to convert a literal with the wrong type.
