Struct CuptiLibrary 

pub struct CuptiLibrary { /* private fields */ }

A runtime-loaded handle to libcupti.so exposing the Activity API.

Loading is entirely lazy and fallible: there is no CUPTI on a machine without the CUDA toolkit profiling components, in which case CuptiLibrary::load returns an Err. The handle keeps the Library alive for the lifetime of the resolved function pointers.

Implementations

impl CuptiLibrary

pub fn load() -> Result<Self, DriverLoadError>

Attempt to load CUPTI and confirm the Activity API symbols are present.

Errors

• DriverLoadError::LibraryNotFound if no CUPTI library can be opened (the common case on a host without the profiling components).
• DriverLoadError::SymbolNotFound if the library opens but is missing a required Activity API entry point.

pub fn supports_register_callbacks(&self) -> bool
