Enum ResourceError 

pub enum ResourceError {
    OutOfBudget {
        requested: usize,
        current: usize,
        remaining: usize,
        limit: 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 exact accounting state captured at the rejecting decision point so callers can report cumulative pressure.

Fields

requested: usize

current: usize

remaining: usize

limit: 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.
