Enum InputError 

#[non_exhaustive]
pub enum InputError {
    Limit {
        needed: u64,
        limit: usize,
    },
    RangesDisabled,
    ReadsDisabled,
    Allocation {
        bytes: usize,
        source: TryReserveError,
    },
}

Driver admission or allocation failure, separate from codec/source errors.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Limit

A contiguous request or retained capacity exceeds the input allowance.

Fields

needed: u64

Required payload capacity.

limit: usize

Configured maximum capacity.

RangesDisabled

The configuration allows no stored range descriptors.

ReadsDisabled

The configuration allows no source reads.

Allocation

Fallible storage reservation failed. The original allocator error remains available.

Fields

bytes: usize

Requested allocation size (saturating for descriptor overflow).

source: TryReserveError

Original allocation failure.

Trait Implementations

impl Debug for InputError

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

Formats the value using the given formatter.

impl Display for InputError

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

Formats the value using the given formatter.

impl Error for InputError

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.
