Enum ForgetPayloadError

pub enum ForgetPayloadError<OE> {
    NoSuchEntry,
    WrongEntry,
    OperationError(OE),
}

Returned when forgetting a payload fails.

Variants

NoSuchEntry

No entry for the given subspace and path exists in this store.

WrongEntry

The operation supplied an expected payload_digest, but it did not match the digest of the entry.

OperationError(OE)

Something specific to this store implementation went wrong.

Trait Implementations

impl<OE: Clone> Clone for ForgetPayloadError<OE>

fn clone(&self) -> ForgetPayloadError<OE>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<OE: Debug> Debug for ForgetPayloadError<OE>

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

Formats the value using the given formatter.

impl<OE: Display + Error> Display for ForgetPayloadError<OE>

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

Formats the value using the given formatter.

impl<OE: Display + Error> Error for ForgetPayloadError<OE>

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<OE: Hash> Hash for ForgetPayloadError<OE>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<OE: Ord> Ord for ForgetPayloadError<OE>

fn cmp(&self, other: &ForgetPayloadError<OE>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<OE: PartialEq> PartialEq for ForgetPayloadError<OE>

fn eq(&self, other: &ForgetPayloadError<OE>) -> 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.

impl<OE: PartialOrd> PartialOrd for ForgetPayloadError<OE>

fn partial_cmp(&self, other: &ForgetPayloadError<OE>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
