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.

A backend also says whether the status poisoned the device: some faults (e.g. an illegal address) leave the context unusable, and every later call on it fails with the same code.

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 poisoned(op: &'static str, status: u32) -> Self

A failure rendering the device unusable.

pub fn is_device_poisoned(&self) -> bool

Whether this failure poisoned the device.

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

The entry point that failed.

pub fn status(&self) -> u32

The driver’s own status code.

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
