Enum StoreError

pub enum StoreError {
    EntryError(EntryError),
    KeyNotFound,
}

the StoreError type enumerates the possible errors that can occur in the store module.

Variants

EntryError(EntryError)

KeyNotFound

An error indicating that the key was not found in the key-value store.

Implementations

impl StoreError

pub const fn is_entry_error(&self) -> bool

Returns true if the enum is StoreError::EntryError otherwise false

pub const fn is_key_not_found(&self) -> bool

Returns true if the enum is StoreError::KeyNotFound otherwise false

Trait Implementations

impl Clone for StoreError

fn clone(&self) -> StoreError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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

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
