Struct SpecializationMap 

pub struct SpecializationMap { /* private fields */ }

A collection of specialization constants for a shader.

Implementations

impl SpecializationMap

pub fn new() -> Self

Create a new empty specialization map.

pub fn define(&mut self, name: &str, default_value: &str, description: &str)

Define a specialization constant with a default value.

pub fn set(&mut self, name: &str, value: &str)

Override a constant’s value.

pub fn get(&self, name: &str) -> Option<&str>

Get the effective value for a constant (override or default).

pub fn len(&self) -> usize

Return the number of defined constants.

pub fn is_empty(&self) -> bool

Check if there are no constants defined.

pub fn apply(&self, source: &str) -> String

Apply specialization constants to a shader source by replacing const {NAME} = {DEFAULT}; patterns with overridden values.

Trait Implementations

impl Clone for SpecializationMap

fn clone(&self) -> SpecializationMap

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SpecializationMap

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

Formats the value using the given formatter.

impl Default for SpecializationMap

fn default() -> SpecializationMap

Returns the “default value” for a type.
