Enum Base64DecodeError 

#[non_exhaustive]
pub enum Base64DecodeError {
    InvalidByte {
        index: usize,
        byte: u8,
    },
    InvalidLength {
        len: usize,
    },
    InvalidLastSymbol {
        index: usize,

    },
    InvalidPadding,
}

Error returned when Base64 decoding rejects caller-owned input.

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.

InvalidByte

The encoded text contains a byte outside the selected Base64 alphabet.

Fields

index: usize

Zero-based byte position of the invalid byte.

byte: u8

Invalid byte value.

InvalidLength

The encoded text length is invalid for Base64 decoding.

Fields

len: usize

Number of bytes in the encoded text.

InvalidLastSymbol

The final non-padding symbol has impossible trailing bits.

Fields

index: usize

Zero-based byte position of the invalid symbol.

byte: u8

Invalid byte value.

InvalidPadding

The encoded text violates the selected padding policy.

Trait Implementations

impl Clone for Base64DecodeError

fn clone(&self) -> Base64DecodeError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Base64DecodeError

impl Debug for Base64DecodeError

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

Formats the value using the given formatter.

impl Display for Base64DecodeError

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

Formats the value using the given formatter.

impl Eq for Base64DecodeError

impl Error for Base64DecodeError

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 Base64DecodeError

fn from(error: DecodeError) -> Self

Converts to this type from the input type.

impl PartialEq for Base64DecodeError

fn eq(&self, other: &Base64DecodeError) -> 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.
