Function crate_conversion_error_class 

pub(crate) fn crate_conversion_error_class() -> &'static [&'static str]

The package crate’s conversion_error_class, from the entry miniextendr_init! registers in MX_CONVERSION_ERROR_CLASS (each package links its own copy of this crate, so it is that package’s), or on wasm32 from the wasm_registry.rs snapshot (#1768). Empty when the crate sets none.
