Enum SystemError 

pub enum SystemError {
    InvalidSpecName,
    SpecVersionNeedsToIncrease,
    FailedToExtractRuntimeVersion,
    NonDefaultComposite,
    NonZeroRefCount,
    CallFiltered,
}

Error for the System pallet

Variants

InvalidSpecName

The name of specification does not match between the current runtime and the new runtime.

SpecVersionNeedsToIncrease

The specification version is not allowed to decrease between the current runtime and the new runtime.

FailedToExtractRuntimeVersion

Failed to extract the runtime version from the new runtime.

Either calling Core_version or decoding RuntimeVersion failed.

NonDefaultComposite

Suicide called when the account has non-default composite data.

NonZeroRefCount

There is a non-zero reference count preventing the account from being purged.

CallFiltered

The origin filter prevent the call to be dispatched.

Implementations

impl SystemError

pub fn as_static_str(&self) -> &'static str

Trait Implementations

impl Clone for SystemError

fn clone(&self) -> SystemError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SystemError

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

Formats the value using the given formatter.

impl Decode for SystemError

fn decode<__CodecInputEdqy: Input>( __codec_input_edqy: &mut __CodecInputEdqy, ) -> Result<Self, Error>

Attempt to deserialise the value from input.

fn decode_into<I>( input: &mut I, dst: &mut MaybeUninit<Self>, ) -> Result<DecodeFinished, Error>

where I: Input,

Attempt to deserialize the value from input into a pre-allocated piece of memory.

fn skip<I>(input: &mut I) -> Result<(), Error>

where I: Input,

Attempt to skip the encoded value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl<'de> Deserialize<'de> for SystemError

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Encode for SystemError

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode_to<__CodecOutputEdqy: Output + ?Sized>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy, )

Convert self to a slice and append it to the destination.

fn encode(&self) -> Vec<u8>

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> R

where F: FnOnce(&[u8]) -> R,

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl EnumInfo for SystemError

fn as_name(&self) -> &'static str

fn as_docs(&self) -> &'static [&'static str]

fn as_short_doc(&self) -> &'static str

impl From<&SystemError> for &'static str

fn from(v: &SystemError) -> Self

Converts to this type from the input type.

impl From<SystemError> for &'static str

fn from(v: SystemError) -> Self

Converts to this type from the input type.

impl PartialEq for SystemError

fn eq(&self, other: &SystemError) -> 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 Serialize for SystemError

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
