Struct ContextOptions 

pub struct ContextOptions {
    pub backends: Backends,
    pub adapter_name: Option<String>,
    pub low_power: bool,
    pub min_storage_buffers_per_stage: u32,
    pub limits_cap: Option<LimitsCap>,
    pub label: String,
}

How the app wants the device made.

Fields

backends: Backends

The backends to load (see crate::backend::compute_backends).

adapter_name: Option<String>

Prefer the adapter called this when present (the app’s setting); else the default choice.

low_power: bool

Ask wgpu for the low-power adapter instead of the high-performance one.

min_storage_buffers_per_stage: u32

The fewest storage buffers per shader stage the app’s kernels bind; fewer is refused.

limits_cap: Option<LimitsCap>

Lower the device limits, to reproduce a smaller adapter (parse_limits_cap).

label: String

The device’s debug label.

Implementations

impl ContextOptions

pub fn new(backends: Backends, label: impl Into<String>) -> Self

The default options for backends: default adapter, high performance, no limit cap.
