Enum Error 

pub enum Error<S>
where
    S: CudaStatus + Send + Sync + 'static,
{
    Status {
        status: S,
    },
    Loader(LoaderError),
    FeatureNotSupported {
        api: &'static str,
        since: CudaVersion,
    },
}

A generic error enum for any safe wrapper crate over a single NVIDIA library. Safe crates may use this directly or compose their own richer Error enum out of its variants.

Variants

Status

The library returned a non-success status code.

Fields

status: S

Loader(LoaderError)

The dynamic loader failed.

FeatureNotSupported

The requested API is newer than the installed driver supports.

Fields

api: &'static str

since: CudaVersion

Implementations

impl<S> Error<S>

where S: CudaStatus + Send + Sync + 'static,

pub fn check(status: S) -> Result<(), Self>

Treat a raw status code as a Result. Success codes yield Ok(()), all others yield Err(Error::Status { .. }).

Trait Implementations

impl<S> Debug for Error<S>

where S: CudaStatus + Send + Sync + 'static + Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<S> Display for Error<S>

where S: CudaStatus + Send + Sync + 'static,

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<S> Error for Error<S>

where S: CudaStatus + Send + Sync + 'static, Self: Debug + Display,

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl<S> From<Error<S>> for BaracudaError

where S: CudaStatus + Send + Sync + 'static,

fn from(err: Error<S>) -> Self

Converts to this type from the input type.

impl<S> From<LoaderError> for Error<S>

where S: CudaStatus + Send + Sync + 'static,

fn from(source: LoaderError) -> Self

Converts to this type from the input type.
