Everything the teller refuses, in its own words.

Variants

Account

accountOf: not did:nostr:<x>, a bare x or a did:nostr Multikey.

Amount

sats: not a whole number of satoshis between 0 and 21 million coins.

Name

newLedger: the name is empty or longer than 80 characters.

NotALedger

checkLedger: not a WebLedger, or no genesis.

HashMismatch

checkLedger: the stored hash is not the hash of the genesis.

Outpoint

credit: the outpoint is not <64 lowercase hex>:<vout>.

ZeroTransfer

transfer: an amount of zero.

Insufficient

transfer, debit: the account holds less than the amount.

Fields

account: String

The first 20 characters of the account’s did (did:nostr: and ten hex digits), as the teller writes it.

has: u64

The balance the account holds.

wanted: u64

The amount asked for.

WithdrawalTooSmall

debit: below crate::MIN_PAY.

DepositLedgerHash

depositAddress: the ledger hash is not 64 lowercase hex.

RequestLedgerHash

requestTags: the ledger hash is not 64 lowercase hex.

Op

requestTags: an op other than join, withdraw or transfer.

NoDestination

requestTags, parseRequest: a withdrawal or transfer with no to.

NotARequest

parseRequest: not kind 3700.

Unverified

parseRequest: the id or the signature does not verify.

OtherLedger

parseRequest: the ledger tag names another ledger.

OpAndId

parseRequest: no valid op, or no id of 8 to 64 lowercase hex.

PayoutTooSmall

planPayout: below crate::MIN_PAY.

Rate

planPayout: a fee rate outside 1 to 1000 sat/vB.

NotCovered

planPayout: every coin together cannot pay the amount and the fee.

Fields

held: u64

The sum of every coin offered.

amount: u64

The amount to pay.

ScriptCheck

signPayout: an input failed the chain’s script check.

Fields

input: usize

The input’s index.

reason: String

The verifier’s reason.

FeeBelowRate

signPayout: the signed transaction is bigger than the fee pays for.

Fields

vsize: u64

The signed transaction’s virtual size.

fee: u64

The plan’s fee.

rate: u64

The plan’s rate.

Key(&'static str)

A key, point, tweak or scalar refused by the key rule (sidestr/spec siding/lib/keys.mjs), in its words.

Address(String)

Not a segwit script under that prefix (address.mjs scriptToAddress returns null; this port refuses).

Encoding

A script or txid that is not hex of the right shape (this port: the teller writes whatever it is given and the kernel’s codec refuses it).

Fields

what: &'static str

Which field.

reason: String

Why it was refused.

Sighash

The chain’s signature hash could not be computed for an input.

Fields

input: usize

The input’s index.

reason: &'static str

The reason the sighash refused.

Event(String)

A Nostr event could not be built or signed (sidestr-nostr’s reason).

NotALedgerEvent

This port’s reading of a ledger event (kind 30333), which the teller’s page does inline: not kind 30333.

LedgerContent(String)

This port: the ledger event’s content is not a ledger document.

NotTheOperators

This port: a ledger event not signed by the ledger’s operator, or for another ledger (the page drops both: “the operator’s own word only”).

Trait Implementations

impl Clone for Error

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for Error

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 PartialEq for Error

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
