Struct NvrtcOpts 

pub struct NvrtcOpts {
    pub ftz: Option<bool>,
    pub maxrregcount: Option<usize>,
    pub name: Option<String>,
    pub use_fast_math: Option<bool>,
    pub lto: bool,
    pub cpp_std: Option<CppStd>,
    pub arch: Option<SmArch>,
    pub name_expressions: Vec<String>,
    pub extra_options: Vec<String>,
    pub include_paths: Vec<String>,
}

Subset of cudarc’s [CompileOptions] exposed at our message surface, plus Phase-5 additions for LTO, C++ standard selection, per-arch SM targeting, name-expression registration, and free-form extra flags.

Fields

ftz: Option<bool>

maxrregcount: Option<usize>

name: Option<String>

use_fast_math: Option<bool>

lto: bool

Phase 5: enable link-time optimisation (-dlto). CUDA 12.0+. Off by default — LTO requires --gpu-architecture=compute_NN (not sm_NN) and a final relocatable-device-code link step, so combining with -rdc=true or wired into a cuLink* flow.

cpp_std: Option<CppStd>

Phase 5: select C++ standard. Passed as --std=c++17 / etc.

arch: Option<SmArch>

Phase 5: target SM architecture. When set, overrides any extra_options --gpu-architecture=… flag.

name_expressions: Vec<String>

Phase 5: name expressions for templated kernels. Each string is a C++ expression (e.g. "my_kernel<float, 256>"); after compile, KernelHandle::lowered_name resolves it to the mangled lowered ABI symbol.

extra_options: Vec<String>

Phase 5: arbitrary extra flags (-D…, -I…, --device-as-default-execution-space).

include_paths: Vec<String>

Phase 5: include search paths (-I…).

Implementations

impl NvrtcOpts

pub fn for_arch(arch: SmArch) -> Self

Convenience constructor selecting an SM arch.

pub fn with_lto(self) -> Self

Builder: enable LTO.

pub fn with_cpp_std(self, std: CppStd) -> Self

Builder: select C++ standard.

pub fn with_name_expression(self, expr: impl Into<String>) -> Self

Builder: register a name expression for nvrtcAddNameExpression.

pub fn with_extra_option(self, opt: impl Into<String>) -> Self

Builder: append a free-form extra option (-D…, etc).

pub fn with_include_path(self, path: impl Into<String>) -> Self

Builder: append an include search path.

pub fn build_flags(&self) -> Vec<String>

Materialise the full vector of NVRTC flags this NvrtcOpts would emit. Used for cache-key hashing and trace-level logging.
