Functions
std::vector< std::string_view >	impeller::compiler::GetShaderBundleTargetPlatformDefines (TargetPlatform platform)
	The platform-discriminating preprocessor defines injected when compiling a bundled shader for platform (for example IMPELLER_TARGET_METAL). These let bundled Flutter GPU shaders specialize for the backend they will run on, matching the defines that Impeller's own shaders receive from the build templates.
std::optional< ShaderBundleConfig >	impeller::compiler::ParseShaderBundleConfig (const std::string &bundle_config_json, std::ostream &error_stream)
	Parse a shader bundle configuration from a given JSON string.
std::optional< fb::shaderbundle::ShaderBundleT >	impeller::compiler::GenerateShaderBundleFlatbuffer (const std::string &bundle_config_json, const SourceOptions &options, std::set< std::string > *out_dependencies=nullptr)
	Parses the JSON shader bundle configuration and invokes the compiler multiple times to produce a shader bundle flatbuffer.
bool	impeller::compiler::GenerateShaderBundle (Switches &switches)
	Parses the JSON shader bundle configuration and invokes the compiler multiple times to produce a shader bundle flatbuffer, which is then output to the sl file.
