Enum Zip321Error 

#[non_exhaustive]
pub enum Zip321Error {
    InvalidBase64(DecodeError),

Errors that may be produced in decoding of payment requests.

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.

InvalidBase64(DecodeError)

A memo field in the ZIP 321 URI was not properly base-64 encoded

MemoBytesError(Error)

A memo value exceeded 512 bytes in length or could not be interpreted as a UTF-8 string when using a valid UTF-8 lead byte.

TooManyPayments(usize)

The ZIP 321 request included more payments than can be created within a single Zcash transaction. The wrapped value is the number of payments in the request.

DuplicateParameter(Param, usize)

Parsing encountered a duplicate ZIP 321 URI parameter for the returned payment index.

TransparentMemo(usize)

The payment at the wrapped index attempted to include a memo when sending to a transparent recipient address, which is not supported by the protocol.

ZeroValuedTransparentOutput(usize)

The payment at the wrapped index requested a zero-valued output to a transparent recipient address, which is disallowed by the Zcash consensus rules.

SproutRecipient(usize)

The payment at the wrapped index requests payment to a Sprout address, which is not supported in payment requests per ZIP 321.

RecipientMissing(usize)

The payment at the wrapped index did not include a recipient address.

ParseError(String)

The ZIP 321 URI was malformed and failed to parse.

Trait Implementations

impl Clone for Zip321Error

fn clone(&self) -> Zip321Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Zip321Error

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

Formats the value using the given formatter.

impl Display for Zip321Error

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

Formats the value using the given formatter.

impl Eq for Zip321Error

impl Error for Zip321Error

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
