ms-codec error type.

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.

Codex32(Error)

Upstream codex32 parse / checksum failure (delegated from rust-codex32).

WrongHrp

HRP was not “ms” (SPEC §4 rule 2).

Fields

got: String

The HRP that was observed.

ThresholdNotZero

Threshold was not 0 (SPEC §4 rule 3).

Fields

got: u8

The threshold-position byte (ASCII digit) that was observed.

ShareIndexNotSecret

Share-index was not ‘s’ — BIP-93 requires ‘s’ for threshold=0 (SPEC §4 rule 4).

Fields

got: char

The share-index character that was observed.

TagInvalidAlphabet

Tag bytes were not in the codex32 alphabet (SPEC §4 rule 5).

Fields

got: [u8; 4]

The 4-byte id-field bytes that failed alphabet validation.

UnknownTag

Tag was structurally valid but not in RESERVED_TAG_TABLE (SPEC §4 rule 6).

Fields

got: [u8; 4]

The 4-byte tag that was not recognized.

ReservedTagNotEmittedInV01

Tag was in RESERVED_TAG_TABLE but reserved-not-emitted in v0.1 (SPEC §4 rule 7, SPEC §3.5.1 encoder symmetry).

Fields

got: [u8; 4]

The 4-byte reserved tag (one of seed/xprv/mnem/prvk in v0.1).

ReservedPrefixViolation

Reserved-prefix byte was not 0x00 (SPEC §4 rule 8).

Fields

got: u8

The non-zero prefix byte that was observed.

UnexpectedStringLength

Total string length was outside the v0.1 emittable set (SPEC §4 rule 9).

Fields

got: usize

The total string length that was observed.

allowed: &'static [usize]

The set of v0.1-emittable lengths.

PayloadLengthMismatch

Payload byte length did not match the tag’s spec (SPEC §3.5, §4 rule 10).

Fields

tag: [u8; 4]

The 4-byte tag whose length set was checked against.

expected: &'static [usize]

The set of valid byte lengths for this tag.

got: usize

The observed payload byte length (after stripping the prefix byte).

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 Error

fn from(e: Error) -> Self

Converts to this type from the input type.
