Enum StoreError 

pub enum StoreError {
    KeyNotFound(DbKey),
    KeyAlreadyExists(String),
    HashAlreadyExists(Hash),
    DataInconsistency(String),
    DbError(Error),
    DeserializationError(Box<ErrorKind>),
}

Variants

KeyNotFound(DbKey)

KeyAlreadyExists(String)

HashAlreadyExists(Hash)

Specialization of key already exists for the common Hash case. Added for avoiding the String allocation

DataInconsistency(String)

DbError(Error)

DeserializationError(Box<ErrorKind>)

Trait Implementations

impl Debug for StoreError

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

Formats the value using the given formatter.

impl Display for StoreError

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

Formats the value using the given formatter.

impl Error for StoreError

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<Box<ErrorKind>> for StoreError

fn from(source: Box<ErrorKind>) -> Self

Converts to this type from the input type.

impl From<Error> for StoreError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl StoreErrorPredicates for StoreError

fn is_key_not_found(&self) -> bool

Returns true if this error represents a missing entry (e.g. key not found).

fn is_already_exists(&self) -> bool

Returns true if this error represents a duplicate write (e.g. key/hash already exists).
