Enum KeyError 

pub enum KeyError {
    NotAnIdentityKey,
    DifficultyOutOfRange(u32),
    RandomnessUnavailable,
    Generate(&'static str),
    Sign(&'static str),
}

Why a key operation refused.

Variants

NotAnIdentityKey

A node_id asked of a key that is not an identity key.

DifficultyOutOfRange(u32)

A puzzle difficulty outside 0 to 256.

RandomnessUnavailable

The operating system gave no randomness.

Generate(&'static str)

Generating a half failed.

Sign(&'static str)

Signing with a half failed.

Trait Implementations

impl Clone for KeyError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for KeyError

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

Formats the value using the given formatter.

impl Display for KeyError

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

Formats the value using the given formatter.

impl Eq for KeyError

impl Error for KeyError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

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

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<KeyError> for BindingError

fn from(e: KeyError) -> Self

Converts to this type from the input type.

impl From<KeyError> for IssuerError

fn from(e: KeyError) -> Self

Converts to this type from the input type.

impl PartialEq for KeyError

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

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
