Enum StorageError 

#[non_exhaustive]
pub enum StorageError {
    Bytes {
        requested: usize,
        limit: usize,
    },
    Objects {
        limit: usize,
    },
    SizeOverflow,
    Allocation(TryReserveError),
    Capacity {
        admitted: usize,
        actual: usize,
    },
    Range,
}

Storage could not be admitted or a requested view was invalid.

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.

Bytes

The requested capacity exceeds the remaining managed byte allowance.

Fields

requested: usize

Bytes requested by this allocation.

limit: usize

Total configured allowance.

Objects

All managed allocation slots are occupied, including empty allocations.

Fields

limit: usize

Total configured allocation slots.

SizeOverflow

Element-count arithmetic overflowed or exceeded addressable storage.

Allocation(TryReserveError)

The allocator refused the admitted allocation.

Capacity

The allocator exposed more capacity than admitted. That temporary allocation is freed before returning; it is never published to a caller.

Fields

admitted: usize

Admitted byte count.

actual: usize

Actual vector capacity in bytes.

Range

A subview lies outside its parent view.

Trait Implementations

impl Debug for StorageError

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

Formats the value using the given formatter.

impl Display for StorageError

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

Formats the value using the given formatter.

impl Error for StorageError

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.
