}

Describes a Sampler.

For use with Device::create_sampler.

Corresponds to WebGPU GPUSamplerDescriptor.

Fields

label: Option<&'a str>

Debug label of the sampler. This will show up in graphics debuggers for easy identification.

address_mode_u: AddressMode

How to deal with out of bounds accesses in the u (i.e. x) direction

address_mode_v: AddressMode

How to deal with out of bounds accesses in the v (i.e. y) direction

address_mode_w: AddressMode

How to deal with out of bounds accesses in the w (i.e. z) direction

mag_filter: FilterMode

How to filter the texture when it needs to be magnified (made larger)

min_filter: FilterMode

How to filter the texture when it needs to be minified (made smaller)

mipmap_filter: FilterMode

How to filter between mip map levels

lod_min_clamp: f32

Minimum level of detail (i.e. mip level) to use

lod_max_clamp: f32

Maximum level of detail (i.e. mip level) to use

compare: Option<CompareFunction>

If this is enabled, this is a comparison sampler using the given comparison function.

anisotropy_clamp: u16

Must be at least 1. If this is not 1, all filter modes must be linear.

border_color: Option<SamplerBorderColor>

Border color to use when address_mode is AddressMode::ClampToBorder

Trait Implementations

impl<'a> Clone for SamplerDescriptor<'a>

fn clone(&self) -> SamplerDescriptor<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for SamplerDescriptor<'a>

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

Formats the value using the given formatter.

impl Default for SamplerDescriptor<'_>

fn default() -> SamplerDescriptor<'_>

Returns the “default value” for a type.

impl<'a> From<SamplerDescriptor<'a>> for ImageSamplerDescriptor

fn from(value: SamplerDescriptor<'_>) -> Self

Converts to this type from the input type.

impl<'a> PartialEq for SamplerDescriptor<'a>

fn eq(&self, other: &SamplerDescriptor<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
