Enum GpuInitError 

pub enum GpuInitError {
    CreateSurface(CreateSurfaceError),
    NoAdapter,
    RequestDevice(RequestDeviceError),
}

Errors GpuRenderer::new surfaces to the host. The host’s expected flow is “try this, fall back to the CPU path on Err”.

Variants

CreateSurface(CreateSurfaceError)

NoAdapter

RequestDevice(RequestDeviceError)

Trait Implementations
