Struct MaterialKey 

pub struct MaterialKey(/* private fields */);

A hash key derived from the content of a PbrMaterial. Two materials that are structurally identical produce the same key.

Implementations

impl MaterialKey

pub fn from_material(m: &PbrMaterial) -> Self

Derive the key from a material by hashing its fields with a simple FNV-1a accumulator. This is not cryptographic — it is only used for cache lookup.

Trait Implementations

impl Clone for MaterialKey

fn clone(&self) -> MaterialKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MaterialKey

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

Formats the value using the given formatter.

impl Hash for MaterialKey

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 MaterialKey

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