Struct ContextOptions 

pub struct ContextOptions {
    pub device_label: String,
    pub backends: Option<Backends>,
}

How a RenderContext should build its instance and request its device.

Every field has a working default, so ContextOptions::default() is the ordinary construction — a field exists here only where a host genuinely has a choice to make, and RenderContext::new takes the defaults.

Fields

device_label: String

Debug label attached to the created wgpu::Device, surfaced by graphics debuggers and in validation messages.

backends: Option<Backends>

Backends the wgpu::Instance is restricted to. None — the default — takes wgpu::Backends::from_env() (the WGPU_BACKEND knob) and falls back to every backend compiled in, which is what a shell wants. A headless caller that must pin one backend regardless of the ambient environment sets it explicitly.
