Struct GpuRequirements 

pub struct GpuRequirements {
    pub required_features: GpuFeatures,
    pub requested_features: GpuFeatures,
    pub additional_wgpu_features: Features,
    pub min_limits: Limits,
}

GPU requirements for a render capability.

Contains required features (must be present), requested features (best-effort), additional raw wgpu features, and minimum device limits.

Fields

required_features: GpuFeatures

Features that must be present (device creation fails if missing).

requested_features: GpuFeatures

Features that are desired but not essential (warns if missing).

additional_wgpu_features: Features

Additional raw wgpu features not covered by GpuFeatures.

min_limits: Limits

Minimum device limits. Merged with other requirements via field-wise max.

Implementations

impl GpuRequirements

pub fn none() -> Self

Create requirements with no features or elevated limits.

pub fn new() -> Self

Create a new requirements builder starting from no requirements.

pub fn require_features(self, features: GpuFeatures) -> Self

Set required GPU features.

pub fn request_features(self, features: GpuFeatures) -> Self

Set requested (best-effort) GPU features.

pub fn with_wgpu_features(self, features: Features) -> Self

Set additional raw wgpu features.

pub fn with_min_limits(self, f: impl FnOnce(&mut Limits)) -> Self

Modify minimum limits via a closure.

Example

GpuRequirements::new().with_min_limits(|l| {
    l.max_binding_array_elements_per_shader_stage = 256;
})

pub fn merge(&mut self, other: &GpuRequirements)

Merge another set of requirements into this one.

Features are unioned, limits are merged via field-wise max.
