Enum DerivationError 

pub enum DerivationError {
    SeedInvalid,
    ContextStringInvalid,
    SubpathEmpty,
}

An error that occurred in cryptovalue derivation.

Variants

SeedInvalid

The provided seed data was invalid. A seed must be between 32 and 252 bytes in length, inclusive.

ContextStringInvalid

The provided context string is invalid; context strings must be non-empty and no greater than 252 bytes in length.

SubpathEmpty

The provided subpath was empty. Empty subpaths are not permitted by this API, as the full-width cryptovalue at the empty subpath would be outside the allowed subtree rooted at m_{context} / zip_number'.

Trait Implementations

impl Clone for DerivationError

fn clone(&self) -> DerivationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DerivationError

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

Formats the value using the given formatter.

impl Display for DerivationError

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

Formats the value using the given formatter.

impl Error for DerivationError

Available on crate feature std only.

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 PartialEq for DerivationError

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

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

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
