Struct EngineUnsupported 

pub struct EngineUnsupported {
    pub adapter_name: String,
    pub missing_flags: DownlevelFlags,
}

An adapter that cannot run the engine: the refusal engine_support returns, naming the adapter and the flags it is missing.

Carries its own diagnosis through std::fmt::Display — the one message a refused adapter surfaces through, shared by the surface path (context::create_engine_surface) and the headless harness (crate::HeadlessRenderer), so both refuse in the same words.

Fields

adapter_name: String

The adapter that was refused, for the diagnosis.

missing_flags: DownlevelFlags

The subset of ENGINE_REQUIRED_DOWNLEVEL_FLAGS this adapter does not report. Never empty in a value that exists: an adapter missing nothing is Ok.
