Enum MutationError 

pub enum MutationError {
    EmptyKey,
    KeyTooLarge {
        length: usize,
        maximum: usize,
    },
    OperationTooLarge {
        length: usize,
        maximum: usize,
    },
    Malformed,
    UnknownKind {
        kind: u8,
    },
}

Failure while validating or decoding a persisted mutation.

Variants

EmptyKey

Empty keys are forbidden.

KeyTooLarge

A key exceeds the stable storage limit.

Fields

length: usize

Actual key length.

maximum: usize

Maximum key length.

OperationTooLarge

The full encoded operation exceeds one log frame.

Fields

length: usize

Actual encoded length.

maximum: usize

Maximum operation length.

Malformed

Persisted bytes do not form one canonical mutation.

UnknownKind

The mutation kind is not defined by this disk format.

Fields

kind: u8

Raw kind byte.

Trait Implementations

impl Clone for MutationError

fn clone(&self) -> MutationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MutationError

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

Formats the value using the given formatter.

impl Display for MutationError

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

Formats the value using the given formatter.

impl Eq for MutationError

impl Error for MutationError

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 From<MutationError> for StorageError

fn from(source: MutationError) -> Self

Converts to this type from the input type.

impl From<MutationError> for MaterializedIndexError

fn from(source: MutationError) -> Self

Converts to this type from the input type.

impl PartialEq for MutationError

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

Equality operator ==.

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

Inequality operator !=.
