Enum base64::DecodeError

pub enum DecodeError {
    InvalidByte(usize, u8),
    InvalidLength,
    InvalidLastSymbol(usize, u8),
}

Errors that can occur while decoding.

Variants

InvalidByte(usize, u8)

An invalid byte was found in the input. The offset and offending byte are provided.

InvalidLength

The length of the input is invalid. A typical cause of this is stray trailing whitespace or other separator bytes. In the case where excess trailing bytes have produced an invalid length and the last byte is also an invalid base64 symbol (as would be the case for whitespace, etc), InvalidByte will be emitted instead of InvalidLength to make the issue easier to debug.

InvalidLastSymbol(usize, u8)

The last non-padding input symbol’s encoded 6 bits have nonzero bits that will be discarded. This is indicative of corrupted or truncated Base64. Unlike InvalidByte, which reports symbols that aren’t in the alphabet, this error is for symbols that are in the alphabet but represent nonsensical encodings.

Trait Implementations

impl Clone for DecodeError

fn clone(&self) -> DecodeError

Returns a copy of the value.

impl Error for DecodeError

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

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

impl PartialEq<DecodeError> for DecodeError

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

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

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

This method tests for !=.
