Struct RendererInitConfig 

pub struct RendererInitConfig {
    pub backends: Option<Backends>,
    pub power_preference: PowerPreference,
    pub required_features: Features,
    pub required_limits: Limits,
    pub depth_format: TextureFormat,
}

Static initialization parameters for the GPU context.

Consumed once during [Renderer::init] to create the wgpu instance, adapter, device, and core resources. These values cannot be changed at runtime without destroying and rebuilding the entire GPU context.

Example

use myth::render::RendererInitConfig;

let config = RendererInitConfig {
    power_preference: wgpu::PowerPreference::LowPower,
    ..Default::default()
};

Fields

backends: Option<Backends>

Force a specific wgpu backend (Vulkan, Metal, DX12, …).

None lets wgpu choose the best available backend for the platform. Override this only when debugging backend-specific issues.

power_preference: PowerPreference

GPU adapter selection preference.

• HighPerformance: Prefer discrete / dedicated GPU (default)
• LowPower: Prefer integrated GPU (better battery life)

required_features: Features

Required wgpu features that must be supported by the adapter.

The engine will fail to initialize if these features are unavailable. Use with caution on WebGPU targets where feature support varies.

required_limits: Limits

Required wgpu limits (max buffer sizes, binding counts, etc.).

depth_format: TextureFormat

Depth buffer texture format.

Defaults to Depth32Float — pure 32-bit floating-point depth with maximum precision and full COPY_SRC/COPY_DST support on all backends (including WebGPU).

Trait Implementations

impl Clone for RendererInitConfig

fn clone(&self) -> RendererInitConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RendererInitConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for RendererInitConfig

fn default() -> RendererInitConfig

Returns the “default value” for a type.
