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.

DlOpenUnknown

The dlopen call failed and system did not report an error.

DlSym

The dlsym call failed.

Fields

§desc: DlDescription

The source error.

DlSymUnknown

The dlsym call failed and system did not report an error.

DlClose

The dlclose call failed.
