Enum SamplerKind 

pub enum SamplerKind {
    LinearRepeat,
    LinearClamp,
    LinearClampNoMip,
    Nearest,
    NearestClampBorder,
    CompareLess,
}

A named, pre-built sampler configuration. Every variant is built once at startup and shared via GlobalSamplers — look one up with GlobalSamplers::get(kind) rather than creating your own wgpu::Sampler.

Variants

LinearRepeat

Linear filtering, tiling (Repeat) address mode, mipmapped.

LinearClamp

Linear filtering, edge-clamped, mipmapped.

LinearClampNoMip

Linear filtering, edge-clamped, no mipmapping (lod_min/max_clamp = 0).

Nearest

Nearest-neighbor filtering, wgpu’s default (repeat) address mode.

NearestClampBorder

Nearest-neighbor filtering, clamped to a border color. On web this falls back to edge-clamping instead (see descriptor’s docs) since WebGPU has no border-color support.

CompareLess

Linear filtering, edge-clamped, with CompareFunction::Less — for shadow-map textureSampleCompare.

Implementations

impl SamplerKind

pub fn descriptor(&self) -> SamplerDescriptor<'static>

The wgpu::SamplerDescriptor this kind builds.

NearestClampBorder is the one variant that isn’t identical across platforms: WebGPU doesn’t support ClampToBorder/a border color at all, so on wasm32 this silently downgrades to ClampToEdge (no border color) instead — sampling outside [0, 1] UV will read edge texels on web instead of the border color you’d get natively. If your material depends on the border being visually distinct from the edge, this is a real cross-platform behavior difference to account for, not just an implementation detail.
