Enum casperlabs_contract_ffi::value::account::AddKeyFailure

#[repr(i32)]
pub enum AddKeyFailure {
    MaxKeysLimit,
    DuplicateKey,
    PermissionDenied,
}

Represents an error that happens when trying to add a new associated key on an account.

It is represented by i32 to be easily able to transform this value in an out through FFI boundaries as a number.

The explicit numbering of the variants is done on purpose and whenever you plan to add new variant, you should always extend it, and add a variant that does not exist already. When adding new variants you should also remember to change From<i32> for AddKeyFailure.

This way we can ensure safety and backwards compatibility. Any changes should be carefully reviewed and tested.

impl Eq for AddKeyFailure

impl Fail for AddKeyFailure

fn name(&self) -> Option<&str>

Returns the "name" of the error.

fn cause(&self) -> Option<&dyn Fail>

Returns a reference to the underlying cause of this failure, if it is an error that wraps other errors.

fn backtrace(&self) -> Option<&Backtrace>

Returns a reference to the Backtrace carried by this failure, if it carries one.

fn context<D>(self, context: D) -> Context<D> where
    D: Display + Send + Sync + 'static, 

Provides context for this failure.

fn compat(self) -> Compat<Self>

Wraps this failure in a compatibility wrapper that implements std::error::Error.

impl From<AddKeyFailure> for Error

fn from(error: AddKeyFailure) -> Self

Performs the conversion.

impl PartialEq<AddKeyFailure> for AddKeyFailure

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

This method tests for self and other values to be equal, and is used by ==.

#[must_use] fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl StructuralEq for AddKeyFailure

impl StructuralPartialEq for AddKeyFailure

impl TryFrom<i32> for AddKeyFailure

convert from i32 representation of [AddKeyFailure]

type Error = TryFromIntError

The type returned in the event of a conversion error.

fn try_from(value: i32) -> Result<Self, Self::Error>

Performs the conversion.
