Structs

UniversalOptions

Options valid for every solver, including NLP backends. Each backend’s options struct embeds this via HasUniversal; the UniversalOptionsExt blanket impl then provides typed builder setters.

Traits

HasUniversal

Implemented by every backend-specific options struct. Gives the UniversalOptionsExt blanket impl access to the embedded UniversalOptions.

UniversalOptionsExt

Builder setters available on every backend options struct.
