Enum DecodeError 

pub enum DecodeError {
    InvalidCharacter(char),
    Truncated(u32),
    UnusedBits(u32),
}

Why a string is not valid lowercase unpadded base32.

Variants

InvalidCharacter(char)

A character outside the alphabet, including =: padding is refused rather than tolerated, because the protocol specifies unpadded and a padded string is a second encoding of the same bytes.

Truncated(u32)

A length that no whole number of bytes can produce, such as a single leftover character. The value is how many bits were left over.

UnusedBits(u32)

The final character carries bits that the decoded bytes do not use. Decoding would silently discard them and re-encoding would produce a different string, so it is refused.

Trait Implementations

impl Clone for DecodeError

fn clone(&self) -> DecodeError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DecodeError

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

Formats the value using the given formatter.

impl Display for DecodeError

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

Formats the value using the given formatter.

impl Error for DecodeError

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<DecodeError> for CidError

fn from(source: DecodeError) -> Self

Converts to this type from the input type.

impl PartialEq for DecodeError

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

Tests for self and other values to be equal, and is used by ==.

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

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