Enum PayloadAppendError

pub enum PayloadAppendError<PayloadSourceError, OE> {
    NoSuchEntry,
    WrongEntry,
    TooManyBytes,
    DigestMismatch,
    SourceError {
        source_error: PayloadSourceError,
        total_length_now_available: u64,
    },
    OperationError(OE),
}

Returned when a payload fails to be appended into the Store.

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.

TooManyBytes

The payload source produced more bytes than were expected for this payload.

DigestMismatch

The completed payload’s digest is not what was expected.

SourceError

The source that provided the payload bytes emitted an error.

Fields

source_error: PayloadSourceError

total_length_now_available: u64

Returns how many bytes of payload the store now stores for this entry.

OperationError(OE)

Something specific to this store implementation went wrong.

Trait Implementations

impl<PayloadSourceError: Clone, OE: Clone> Clone for PayloadAppendError<PayloadSourceError, OE>

impl<PayloadSourceError: Debug, OE: Debug> Debug for PayloadAppendError<PayloadSourceError, OE>

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

Formats the value using the given formatter.

impl<PayloadSourceError: Display + Error, OE: Display + Error> Display for PayloadAppendError<PayloadSourceError, OE>

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

Formats the value using the given formatter.

impl<PayloadSourceError: Display + Error, OE: Display + Error> Error for PayloadAppendError<PayloadSourceError, 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<PayloadSourceError: Hash, OE: Hash> Hash for PayloadAppendError<PayloadSourceError, 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<PayloadSourceError: Ord, OE: Ord> Ord for PayloadAppendError<PayloadSourceError, OE>

fn cmp(&self, other: &PayloadAppendError<PayloadSourceError, 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<PayloadSourceError: PartialEq, OE: PartialEq> PartialEq for PayloadAppendError<PayloadSourceError, OE>

fn eq(&self, other: &PayloadAppendError<PayloadSourceError, 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.

fn partial_cmp( &self, other: &PayloadAppendError<PayloadSourceError, 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.
