struct FShaderCompilerOutput

The output of the shader compiler. Bump ShaderCompileWorkerOutputVersion if FShaderCompilerOutput changes

FString	ModifiedEntryPointName	Use this field to store the entry point name if it's modified as part of the shader format's compilation process.
FString	ModifiedShaderSource	Use this field to store the shader source code if it's modified as part of the shader format's compilation process.

Type	Name	Description
	FShaderCompilerOutput ()
PRAGMA_DISABLE_DEPRECATION_WARNINGS	FShaderCompilerOutput ( FShaderCompilerOutput&& )	Explicitly-defaulted copy/move ctors & assignment operators are needed temporarily due to deprecation of bFailedRemovingUnused/bUsedHLSLccCompiler fields.
	FShaderCompilerOutput ( const FShaderCompilerOutput& )

Type	Name	Description
void	CompressOutput ( FName ShaderCompressionFormat, FOodleDataCompression::ECompressor OodleCompressor, FOodleDataCompression::ECompressionLevel OodleLevel )	Calls GenerateOutputHash() before the compression, replaces FShaderCode with the compressed data (if compression result was smaller).
void	GenerateOutputHash ()	Generates OutputHash from the compiler output.
void	SerializeShaderCodeValidation ()	Add optional data in ShaderCode to perform additional shader input validation at runtime
