Enum Bech32Error 

pub enum Bech32Error {
    InvalidHrp,
    ConversionFailed,
    OperationFailed,
    UnexpectedHrp {
        expected: String,
        got: String,
    },
    InvalidLength {
        expected: usize,
        got: usize,
    },
}

Errors from Bech32 (BIP-173) and Bech32m (BIP-350) decoding. Debug builds include detailed context; release builds use generic messages. Errors produced when decoding Bech32 (BIP-173) or Bech32m (BIP-350) strings.

Requires feature encoding-bech32 or encoding-bech32m.

In debug builds UnexpectedHrp and InvalidLength carry expected/got fields for development debugging. In release builds these variants are opaque to prevent leaking expected-length or HRP metadata.

Variants

InvalidHrp

The Human-Readable Part (HRP) is invalid.

ConversionFailed

Bit conversion during encoding/decoding failed.

Currently unreachable. After CheckedHrpstring::new() succeeds, the .byte_iter() iterator is infallible — all bit-conversion happens during the new() call and any failure surfaces as OperationFailed instead. This variant is preserved as public API for forward compatibility should a fallible conversion path be introduced in a future release of the bech32 crate.

OperationFailed

General bech32 operation failure.

UnexpectedHrp

Unexpected HRP in debug builds (detailed).

Fields

expected: String

The HRP the caller required.

got: String

The HRP found in the input string.

InvalidLength

Length mismatch in debug builds (detailed).

Fields

expected: usize

Number of bytes the target type requires.

got: usize

Number of bytes actually decoded.

Trait Implementations

impl Clone for Bech32Error

fn clone(&self) -> Bech32Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Bech32Error

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

Formats the value using the given formatter.

impl Display for Bech32Error

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

Formats the value using the given formatter.

impl Error for Bech32Error

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 Bech32Error

fn eq(&self, other: &Bech32Error) -> 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.
