Enum DeriveError 

#[non_exhaustive]
pub enum DeriveError {
    Mnemonic(Error),
    Path(String),
    Crypto(String),
    Input(String),
    AddressEncoding(String),
}

Errors produced by HD derivation, mnemonic handling, and address encoding.

Variants partition failures by domain:

• Mnemonic — BIP-39 decode / encode failures.
• Path — invalid or malformed derivation paths.
• Crypto — underlying cryptographic primitive failures (HMAC, BIP-32 / SLIP-10 key math, PBKDF2, BLAKE2, secp256k1, etc.).
• Input — caller-supplied inputs that fail validation (word count, hex encoding, empty password, prefix expansion, index overflow, unknown derivation style).
• AddressEncoding — chain-specific address encoding failures (Bech32 / Bech32m HRP, base58check, base32, …).

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)

BIP-39 mnemonic decoding / encoding failed.

Path(String)

Derivation path is malformed or unsupported.

Crypto(String)

A cryptographic primitive (HMAC, BIP-32 / SLIP-10, PBKDF2, BLAKE2, secp256k1, …) failed.

Input(String)

Caller-supplied input failed validation (word count, hex, index, unknown derivation style, …).

AddressEncoding(String)

Chain-specific address encoding failed (Bech32 / Bech32m, base58, base32, …).

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.
