Errors that can occur during wallet operations.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Mnemonic(Error)

Invalid mnemonic phrase.

InvalidWordCount(usize)

Invalid word count for mnemonic.

PrefixTooShort

Mnemonic prefix is too short for unambiguous expansion.

Fields

prefix: String

The prefix that was too short.

min_len: usize

Minimum required prefix length.

UnknownPrefix(String)

Mnemonic prefix does not match any word in the wordlist.

AmbiguousPrefix

Mnemonic prefix matches multiple words in the wordlist.

Fields

prefix: String

The ambiguous prefix.

candidates: Vec<String>

Words that match the prefix.

IndexOverflow

Index overflow in batch derivation.

InvalidHex(String)

Stored hex material is malformed.

Produced by the byte-level accessors on DerivedAccount / DerivedAddress when decoding their hex fields. Derivers in this workspace never produce malformed hex, so this error indicates externally-constructed data.

Trait Implementations

impl Debug for DeriveError

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

Formats the value using the given formatter.

impl Display for DeriveError

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

Formats the value using the given formatter.

impl Error for DeriveError

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<Error> for DeriveError

fn from(source: Error) -> Self

Converts to this type from the input type.
