Struct DriverError 

pub struct DriverError { /* private fields */ }

A driver entry point that failed, named by what was called.

The status is kept as a number rather than decoded: each API numbers its own enum and neither table belongs here. Naming the entry point is what makes the number searchable in the vendor’s headers.

Implementations

impl DriverError

pub fn new(op: &'static str, status: u32) -> Self

A failure a binding already turned into an error type of its own, named by the entry point that produced it.

checked is the answer wherever the status is still a number. A binding that returns a typed result — cudarc’s CUresult wrapper — has already consumed the number, and this is how the entry point’s name is put back on it.

pub fn op(&self) -> &'static str

The entry point that failed.

pub fn status(&self) -> u32

The driver’s own status code.

impl Eq for DriverError

impl Error for DriverError

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
