Enum DecodeError

pub enum DecodeError {
    InvalidChar {
        char: char,
        index: usize,
    },
    InvalidLength {
        length: usize,
    },
}

Error generated when decoding invalid data

InvalidChar: a character to be decoded is either:

1. not in the decoding list of characters at all or
2. positioned at the end of a sequence such that this char is impossible (contains bits in positions, at the end, that make this not actually properly encoded data)

InvalidLength: The remainder of the length of the sequence to be decoded is an impossible length for valid decodable sequences (e.g. official base64 can never generate unpadded encoded sequences of strings with a length remainder of 1, when divided by 4 – only 2, 3, or 4)

Note that for decoding integers, invalid length is simply that the length is too long for that size of integer.

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, f: &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 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.
