Enum casperlabs_contract_ffi::value::account::RemoveKeyFailure

#[repr(i32)]
pub enum RemoveKeyFailure {
    MissingKey,
    PermissionDenied,
    ThresholdViolation,
}

Represents an error that happens when trying to remove an associated key from 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 RemoveKeyFailure.

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

Variants

MissingKey

Key does not exist in the list of associated keys.

PermissionDenied

ThresholdViolation

impl Eq for RemoveKeyFailure

impl Fail for RemoveKeyFailure

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<RemoveKeyFailure> for Error

fn from(error: RemoveKeyFailure) -> Self

Performs the conversion.

impl PartialEq<RemoveKeyFailure> for RemoveKeyFailure

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