Enum ResourceError 

pub enum ResourceError {
    OutOfBudget {
        requested: usize,
        remaining: usize,
    },
    Driver(String),
    StreamMisuse(String),
    UseAfterFree {
        generation: Generation,
    },
    OutOfBounds {
        generation: Generation,
    },
}

Errors returned by resource implementations. Distinct variants for the cases stress tests need to pin (out-of-budget vs CUDA driver failure vs use-after-free etc.).

Variants

OutOfBudget

The requested allocation would exceed the resource’s budget. Carries the requested bytes and the remaining budget so tests can assert deterministic refusal.

Fields

requested: usize

remaining: usize

Driver(String)

CUDA driver returned an error. Carries the wrapped message.

StreamMisuse(String)

A stream-ordered contract was violated (e.g. dealloc on a stream that does not match the alloc stream without an intervening sync).

UseAfterFree

A debug-guard or logging adaptor detected a use-after-free or double-free. Hard error in debug builds; surfaced upward.

Fields

generation: Generation

OutOfBounds

A debug-guard adaptor detected an out-of-bounds write past a canary boundary.

Fields

generation: Generation

Trait Implementations

impl Debug for ResourceError

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

Formats the value using the given formatter.

impl Display for ResourceError

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

Formats the value using the given formatter.

impl Error for ResourceError

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.
