Errors that could occur when decoding a Base58 encoded 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.

BufferTooSmall

The output buffer was too small to contain the entire input.

InvalidCharacter

Fields

character: char

The unexpected character.

index: usize

The (byte) index in the input string the character was at.

The input contained a character that was not part of the current Base58 alphabet.

NonAsciiCharacter

Fields

index: usize

The (byte) index in the input string the start of the character was at.

The input contained a multi-byte (or non-utf8) character which is unsupported by this Base58 decoder.

InvalidChecksum

Fields

checksum: [u8; 4]

The given checksum

expected_checksum: [u8; 4]

The checksum calculated for the payload

Available on crate features check or cb58 only.

The checksum did not match the payload bytes

InvalidVersion

Fields

ver: u8

The given version

expected_ver: u8

The expected version

Available on crate features check or cb58 only.

The version did not match the payload bytes

NoChecksum

Available on crate features check or cb58 only.

Not enough bytes to have both a checksum and a payload (less than to CHECKSUM_LEN)

Implementations

impl Error

pub const fn unwrap_const(self) -> !

Panic with an error message based on this error. This cannot include any of the dynamic content because formatting in const is not yet possible.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy 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, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

Available on crate feature std only.

fn source(&self) -> Option<&(dyn Error + 'static)>

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: &Error) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Error

impl Eq for Error

impl StructuralPartialEq for Error
