        char: char,
        position: usize,
        input: String,
        valid_chars: String,

    InvalidLength {
        actual: usize,
        expected: String,

    },
}

Errors that can occur during decoding.

Variants

InvalidCharacter

The input contains a character not in the dictionary

Fields

char: char

position: usize

input: String

valid_chars: String

InvalidWord

The input contains a word not in the word dictionary

Fields

word: String

position: usize

input: String

EmptyInput

The input string is empty

InvalidPadding

The padding is malformed or incorrect

InvalidLength

Invalid length for the encoding format

Fields

actual: usize

expected: String

hint: String

Implementations

impl DecodeError

pub fn invalid_character( c: char, position: usize, input: &str, valid_chars: &str, ) -> Self

Create an InvalidCharacter error with context

pub fn invalid_length( actual: usize, expected: impl Into<String>, hint: impl Into<String>, ) -> Self

Create an InvalidLength error

pub fn invalid_word(word: &str, position: usize, input: &str) -> Self

Create an InvalidWord error for word-based decoding

Trait Implementations

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.
