Enum DecodingError 

#[non_exhaustive]
pub enum DecodingError {
    InvalidBech32(Bech32Error),
    InvalidBase64(Base64Error),
    InvalidHex(HexError),
    InvalidEncoding,
}

Unified error type wrapping format-specific decoding errors (HexError, Base64Error, Bech32Error). Always available; variants depend on enabled features. Unified error type for multi-format decoding operations.

Wraps format-specific errors from hex, base64url, bech32, and bech32m decoders. Always available; variants depend on enabled features. Like the format-specific errors it wraps, this type is heap-free, Copy, and build-invariant.

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.

InvalidBech32(Bech32Error)

The input is not valid Bech32.

InvalidBase64(Base64Error)

The input is not valid Base64url.

InvalidHex(HexError)

The input is not valid hexadecimal.

InvalidEncoding

The encoding could not be identified.

Deliberately carries no hint text — free-form diagnostics derived from the input would embed input data in the error value.

Trait Implementations

impl Clone for DecodingError

fn clone(&self) -> DecodingError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DecodingError

impl Debug for DecodingError

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

Formats the value using the given formatter.

impl Display for DecodingError

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

Formats the value using the given formatter.

impl Eq for DecodingError

impl Error for DecodingError

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 DecodingError

fn eq(&self, other: &DecodingError) -> 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.
