module composer. stores any modules that can be imported into a shader and builds the final shader

Fields

validate: bool

module_sets: HashMap<String, ComposableModuleDefinition>

module_index: HashMap<usize, String>

capabilities: Capabilities

Implementations

impl Composer

pub fn decorated_name(module_name: Option<&str>, item_name: &str) -> String

impl Composer

pub fn non_validating() -> Self

create a non-validating composer. validation errors in the final shader will not be caught, and errors resulting from their use will have bad span data, so codespan reporting will fail. use default() to create a validating composer.

pub fn with_capabilities(self, capabilities: Capabilities) -> Self

specify capabilities to be used for naga module generation. purges any existing modules

pub fn contains_module(&self, module_name: &str) -> bool

check if a module with the given name has been added

pub fn add_composable_module( &mut self, desc: ComposableModuleDescriptor<'_> ) -> Result<&ComposableModuleDefinition, ComposerError>

add a composable module to the composer. all modules imported by this module must already have been added

pub fn remove_composable_module(&mut self, module_name: &str)

remove a composable module. also removes modules that depend on this module, as we cannot be sure about the completeness of their effective shader defs any more…

pub fn make_naga_module( &mut self, desc: NagaModuleDescriptor<'_> ) -> Result<Module, ComposerError>

build a naga shader module

Trait Implementations

impl Debug for Composer

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

Formats the value using the given formatter.

impl Default for Composer

fn default() -> Self

Returns the “default value” for a type.
