Struct ShaderDependencyGraph 

pub struct ShaderDependencyGraph { /* private fields */ }

Tracks which shaders depend on (include) which other shaders.

When a shader is modified, all shaders that depend on it (transitively) also need to be recompiled.

Implementations

impl ShaderDependencyGraph

pub fn new() -> Self

Create an empty dependency graph.

pub fn add_dependency( &mut self, dependent: impl Into<String>, dependency: impl Into<String>, )

Record that shader dependent depends on dependency.

pub fn direct_dependents(&self, dependency: &str) -> Vec<&str>

Return all shaders that directly depend on dependency.

pub fn transitive_dependents(&self, changed_shader: &str) -> Vec<String>

Return all shaders that transitively depend on changed_shader (BFS / DFS over the dependency graph).

pub fn direct_dependencies(&self, shader: &str) -> &[String]

Return the direct dependencies of shader.

pub fn shaders_with_deps(&self) -> Vec<&str>

Return all shader names that have any recorded dependencies.

Trait Implementations

impl Debug for ShaderDependencyGraph

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

Formats the value using the given formatter.

impl Default for ShaderDependencyGraph

fn default() -> ShaderDependencyGraph

Returns the “default value” for a type.
