Struct SamplerKey 

pub struct SamplerKey {
    pub address_mode_u: AddressMode,
    pub address_mode_v: AddressMode,
    pub address_mode_w: AddressMode,
    pub mag_filter: FilterMode,
    pub min_filter: FilterMode,
    pub mipmap_filter: FilterMode,
    pub lod_min_clamp: u32,
    pub lod_max_clamp: u32,
    pub compare: Option<CompareFunction>,
    pub anisotropy_clamp: u16,
    pub border_color: Option<SamplerBorderColor>,
}

A hashable key for sampler descriptors.

wgpu::SamplerDescriptor doesn’t implement Hash, so we need this wrapper.

Fields

address_mode_u: AddressMode

Address mode for U coordinate

address_mode_v: AddressMode

Address mode for V coordinate

address_mode_w: AddressMode

Address mode for W coordinate

mag_filter: FilterMode

Mipmap filter

lod_min_clamp: u32

Minimum LOD clamp

lod_max_clamp: u32

Maximum LOD clamp

compare: Option<CompareFunction>

Comparison function (if any)

anisotropy_clamp: u16

Anisotropy clamp (1-16)

border_color: Option<SamplerBorderColor>

Border color (for ClampToBorder address mode)

Implementations

impl SamplerKey

pub fn nearest_repeat() -> Self

Create a key for a repeating nearest (point) sampler.

pub fn linear_mirror() -> Self

Create a key for a mirrored linear sampler.

pub fn nearest_mirror() -> Self

Create a key for a mirrored nearest (point) sampler.

pub fn from_descriptor(desc: &SamplerDescriptor<'_>) -> Self

Create a key from a sampler descriptor.

pub fn to_descriptor<'a>(&self, label: Option<&'a str>) -> SamplerDescriptor<'a>

Create a descriptor from this key.

pub fn linear() -> Self

Create a key for a default linear sampler.

pub fn nearest() -> Self

Create a key for a default nearest (point) sampler.

pub fn linear_repeat() -> Self

Create a key for a repeating linear sampler.

Trait Implementations

impl Clone for SamplerKey

fn clone(&self) -> SamplerKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SamplerKey

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

Formats the value using the given formatter.

impl Hash for SamplerKey

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SamplerKey

fn eq(&self, other: &SamplerKey) -> 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.
