Struct HeadlessOptions 

pub struct HeadlessOptions {
    pub backend_hint: Option<String>,
    pub expect_adapter: Option<String>,
    pub expect_backend: Option<String>,
}

How a HeadlessRenderer should pick, and then verify, its GPU.

Fields

backend_hint: Option<String>

Backend(s) to restrict adapter enumeration to, as a comma-separated list (vulkan, metal, dx12, gl, vulkan,metal, …).

A hint: WGPU_BACKEND wins when it is set, so an operator can pin the backend of a run without editing the caller.

expect_adapter: Option<String>

Adapter name the resolved adapter must match (case-insensitive substring). Overrides GOLDEN_EXPECT_ADAPTER_ENV_VAR when set.

expect_backend: Option<String>

Backend the resolved adapter must be on (case-insensitive, whole word). Overrides GOLDEN_EXPECT_BACKEND_ENV_VAR when set.
