By taking the std::string by value in the constructor, this allows for
certain situations where copies can be elided entirely (when moving an
instance into the constructor)
e.g.
std::string var = ...
...
... = LiteralString(std::move(var)) // Or whatever other initialization
// is done.
No copy will be done in this case, the move transfers it into the
constructor, and then the move within the initializer list transfers it
into the member variable.
tl;dr: This allows the calling code to potentially construct less
std::string instances by allowing moving into the parameters themselves.

Sirit
A runtime SPIR-V assembler. It aims to ease dynamic SPIR-V code generation
without calling external applications (like Khronos' spirv-as)
Its design aims to move code that does not belong to the application in the library without, limitting its functionality.
What it does for you:
- Sort declaration opcodes
- Handle types and constant duplicates
- Emit SPIR-V opcodes
What does not do for you:
- Avoid ID duplicates (emitting the same instruction twice)
- Dump code to disk
- Handle code blocks/branches
- Compile from a higher level language
It's in early stages of development, many instructions are missing since they are written manually instead of being generated from a file.
Example
class MyModule : public Sirit::Module {
public:
MyModule() {}
~MyModule() = default;
void Generate() {
AddCapability(spv::Capability::Shader);
SetMemoryModel(spv::AddressingModel::Logical, spv::MemoryModel::GLSL450);
auto main_type{TypeFunction(TypeVoid())};
auto main_func{Emit(OpFunction(TypeVoid(), spv::FunctionControlMask::MaskNone, main_type))};
Emit(OpLabel());
Emit(OpReturn());
Emit(OpFunctionEnd());
AddEntryPoint(spv::ExecutionModel::Vertex, main_func, "main");
}
};
// Then...
MyModule module;
module.Generate();
std::vector<std::uint8_t> code{module.Assemble()};
