Enum RejectCode

pub enum RejectCode {
    SysFatal = 1,
    SysTransient = 2,
    DestinationInvalid = 3,
    CanisterReject = 4,
    CanisterError = 5,
    SysUnknown = 6,
}

Reject codes are integers that canisters should pass to msg.reject system API calls. These errors are designed for programmatic error handling, not for end-users. They are also used for classification of user-facing errors.

Trait Implementations

impl Clone for RejectCode

fn clone(&self) -> RejectCode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RejectCode

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for RejectCode

fn deserialize<__D>( __deserializer: __D, ) -> Result<RejectCode, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for RejectCode

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

Formats the value using the given formatter.

impl From<ErrorCode> for RejectCode

fn from(err: ErrorCode) -> RejectCode

Converts to this type from the input type.

impl Hash for RejectCode

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

where __H: Hasher,

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 IntoEnumIterator for RejectCode

type Iterator = RejectCodeIter

fn iter() -> RejectCodeIter

impl PartialEq for RejectCode

fn eq(&self, other: &RejectCode) -> bool

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

const 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 RejectCode

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<u64> for RejectCode

type Error = TryFromError

The type returned in the event of a conversion error.

fn try_from( code: u64, ) -> Result<RejectCode, <RejectCode as TryFrom<u64>>::Error>

Performs the conversion.
