Enum MutateStorageError

pub enum MutateStorageError<T, E> {
    ConcurrentModification(T),
    ValueFunctionFailed(E),
}

Possible errors when mutating a storage value.

Variants

ConcurrentModification(T)

The underlying db failed to update due to a concurrent modification. Contains the new value that was not stored.

ValueFunctionFailed(E)

The function given to us to create the value to be stored failed. May be used to signal that having looked at the existing value, they don’t want to mutate it.

Trait Implementations

impl<T: Debug, E: Debug> Debug for MutateStorageError<T, E>

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

Formats the value using the given formatter.

impl<T: PartialEq, E: PartialEq> PartialEq for MutateStorageError<T, E>

fn eq(&self, other: &MutateStorageError<T, E>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
