Error produced when decoding a NIP-19 string.

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.

TooLong

The input exceeded MAX_NIP19_LENGTH.

Fields

len: usize

Length of the rejected input.

max: usize

The cap that was exceeded.

Decode(CheckedHrpstringError)

The string is not valid bech32 with the expected checksum.

UnknownHrp(String)

The HRP is not one of the NIP-19 prefixes.

UnexpectedHrp

The HRP did not match the expected entity type.

Fields

expected: &'static str

Expected lowercase HRP.

got: String

Actual lowercase HRP.

InvalidPayloadLength

A fixed-size payload had the wrong length.

Fields

expected: usize

Required number of bytes.

got: usize

Number of bytes seen.

MissingTlv

A required TLV record was missing.

Fields

tag: u8

Tag of the missing record.

InvalidKindLength

A kind TLV had the wrong length (must be 4 bytes).

Fields

got: usize

Number of bytes provided.

KindOutOfRange

A kind TLV held a value that exceeds u16::MAX; nula’s Kind only stores 16-bit kinds even though NIP-19 reserves 32 bits.

Fields

raw: u32

Raw 32-bit value decoded from the TLV.

InvalidRelayUtf8(Utf8Error)

A relay TLV was not valid UTF-8.

Tlv(TlvError)

Forwarded TLV decoding error.

PublicKey(PublicKeyError)

Forwarded public-key validation error.

SecretKey(SecretKeyError)

Forwarded secret-key validation error.

EventId(EventIdError)

Forwarded event-id validation error.

RelayUrl(RelayUrlError)

Forwarded relay-URL validation error.

Trait Implementations

impl Debug for FromBech32Error

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

Formats the value using the given formatter.

impl Display for FromBech32Error

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

Formats the value using the given formatter.

impl Error for FromBech32Error

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
