Enum Error 

pub enum Error {
    CapacityExceeded {
        max_bytes: usize,
    },
    BadSlot {
        size: usize,
        key_len: usize,
    },
    BadShardCount {
        got: usize,
    },
    BlobTooLarge {
        len: usize,
        max_blob: usize,
    },
    ValueTooLarge {
        len: usize,
    },
    Corrupt(&'static str),
}

Errors returned by storage operations. No operation in this crate panics on resource exhaustion — capacity problems are always typed errors. (Contract violations — a wrong key length, an out-of-range id — panic, because they are caller bugs, not runtime conditions; each method documents its panics.)

Variants

CapacityExceeded

Growing a byte pool would exceed the structure’s configured max_bytes ceiling.

Fields

max_bytes: usize

The configured ceiling that would have been crossed.

BadSlot

The Slot layout constants are invalid.

Fields

size: usize

Declared Slot::SIZE.

key_len: usize

Declared Slot::KEY_LEN.

BadShardCount

ArenaCfg::shards is not a non-zero power of two.

Fields

got: usize

The rejected shard count.

BlobTooLarge

A blob passed to BlobHeap::push is longer than the configured max_blob.

Fields

len: usize

Length of the rejected blob.

max_blob: usize

The configured per-blob ceiling.

ValueTooLarge

A value passed to ChunkPool::push is longer than a chunk’s payload (CHUNK_PAYLOAD bytes) and can never fit without crossing a chunk boundary.

Fields

len: usize

Length of the rejected value.

Corrupt(&'static str)

A serialized image failed load-time validation (load methods).

The message names the violated invariant. Loading never panics on arbitrary bytes — every inconsistency maps to this variant.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Error

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Eq for Error

impl Error for Error

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.

impl PartialEq for Error

fn eq(&self, other: &Error) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
