Struct CuestHandleOptions 

pub struct CuestHandleOptions {
    pub jit_cache_dir: Option<PathBuf>,
    pub jit_compile_threads: Option<i32>,
    pub max_gauss_hermite: Option<u64>,
    pub max_l_solid_harmonic: Option<u64>,
    pub max_rys: Option<u64>,
}

Options for CuestContext::with_options.

The defaults (all fields None) reproduce cuEST’s default handle parameters. For JIT-related options and semantics, see the cuEST documentation.

Fields

jit_cache_dir: Option<PathBuf>

JIT kernel cache directory.

None uses the cuEST default (~/.cuest_cache/cuest-cuda<N>-v<version>/), which requires the HOME environment variable to be set; set this explicitly in sandboxes, CI, and tests. cuEST rejects unsafe or unwritable directories.

jit_compile_threads: Option<i32>

Number of parallel JIT precompile worker threads (>= 1, clamped to 256 by cuEST). cuEST default: 16.

max_gauss_hermite: Option<u64>

Maximum number of Gauss-Hermite quadrature points. cuEST default: 20.

max_l_solid_harmonic: Option<u64>

Highest angular momentum for solid harmonics. cuEST default: 10.

max_rys: Option<u64>

Maximum number of Rys quadrature points (0 selects the largest available). cuEST default: 0.
