Struct RefpropLibrary 

pub struct RefpropLibrary { /* private fields */ }

Holds a dynamically-loaded REFPROP shared library with pre-resolved function pointers for zero-overhead calls.

All function symbols are resolved once at construction time. If any required symbol is missing the constructor returns an error instead of panicking later.

All methods are unsafe because they forward raw pointers to Fortran code that cannot be verified by the Rust compiler.

Implementations

impl RefpropLibrary

pub fn load_from_dir(dir: &Path) -> Result<Self, RefpropSysError>

Try to load the REFPROP shared library from a directory that contains the DLL / .so. Common file names are tried automatically.

On 64-bit Windows the 64-bit DLL (REFPRP64.DLL) is tried first. If a candidate file exists but cannot be loaded (e.g. architecture mismatch), the next candidate is tried.

All required symbols are resolved eagerly. If any symbol is missing, an error is returned immediately.

pub fn load_from_file(path: &Path) -> Result<Self, RefpropSysError>

Load the REFPROP shared library from an exact file path.
