Struct ShaderKey 

pub struct ShaderKey {
    pub name: String,
    pub defines: Vec<(String, String)>,
}

Uniquely identifies a compiled shader variant.

Two keys are equal when the base shader name and all defines match.

Fields

name: String

The base shader name (e.g. "sph_density").

defines: Vec<(String, String)>

Sorted define pairs (KEY, VALUE) baked into this variant.

Implementations

impl ShaderKey

pub fn new(name: impl Into<String>, defines: &HashMap<String, String>) -> Self

Create a key from a name and an unsorted define map.

pub fn bare(name: impl Into<String>) -> Self

Create a key with no defines.

pub fn fingerprint(&self) -> String

Return a deterministic string fingerprint suitable for file names.

Trait Implementations

impl Clone for ShaderKey

fn clone(&self) -> ShaderKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ShaderKey

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

Formats the value using the given formatter.

impl Hash for ShaderKey

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 ShaderKey

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