Enum casperlabs_contract_ffi::value::account::UpdateKeyFailure

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

Represents an error that happens when trying to update the value under a public key associated with an account.

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

For backwards compatibility, the variants are explicitly ordered and will not be reordered; variants added in future versions will be appended to extend the enum and in the event that a variant is removed its ordinal will not be reused.

Variants

MissingKey

Key does not exist in the list of associated keys.

PermissionDenied

ThresholdViolation

Trait Implementations

impl Debug for UpdateKeyFailure

impl Eq for UpdateKeyFailure

impl Fail for UpdateKeyFailure

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<UpdateKeyFailure> for Error

fn from(error: UpdateKeyFailure) -> Self

Performs the conversion.

impl PartialEq<UpdateKeyFailure> for UpdateKeyFailure

fn eq(&self, other: &UpdateKeyFailure) -> 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 UpdateKeyFailure

impl StructuralPartialEq for UpdateKeyFailure

impl TryFrom<i32> for UpdateKeyFailure

convert from i32 representation of [UpdateKeyFailure]

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.
