Enum DecodeErrorKind 

#[non_exhaustive]
pub enum DecodeErrorKind {
    InvalidInput,
    InvalidLength,
    InvalidByte,
    InvalidPadding,
    InvalidLineWrap,
    OutputTooSmall,
    StagingTooSmall,
}

Redacted decoding error class.

This type intentionally omits input-derived bytes and indexes so callers can log error classes without logging secret-adjacent input content.

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.

InvalidInput

The encoded input is malformed, but the decoder intentionally does not disclose a more specific error class.

InvalidLength

The encoded input length is impossible for the selected padding policy.

InvalidByte

A byte is not valid for the selected alphabet.

InvalidPadding

Padding is missing, misplaced, or non-canonical.

InvalidLineWrap

Line wrapping is missing, misplaced, or uses the wrong line ending.

OutputTooSmall

The output buffer is too small.

StagingTooSmall

The caller-provided constant-time staging buffer is too small.

Implementations

impl DecodeErrorKind

pub const fn as_str(self) -> &'static str

Returns the stable lowercase identifier for this error class.

Trait Implementations

impl Clone for DecodeErrorKind

fn clone(&self) -> DecodeErrorKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DecodeErrorKind

impl Debug for DecodeErrorKind

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

Formats the value using the given formatter.

impl Display for DecodeErrorKind

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

Formats the value using the given formatter.

impl Eq for DecodeErrorKind

impl PartialEq for DecodeErrorKind

fn eq(&self, other: &DecodeErrorKind) -> 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.
