Enum Error 

pub enum Error {
    InvalidLength,
    InvalidCharacter,
    BufferTooSmall,
}

Errors that can occur during Base64 encoding or decoding operations.

Variants

InvalidLength

The input length is invalid for Base64 decoding.

Base64 encoded data (with padding) must strictly have a length divisible by 4. If the input string is truncated or has incorrect padding length, this error is returned.

InvalidCharacter

An invalid character was encountered during decoding.

This occurs if the input contains bytes that do not belong to the selected Base64 alphabet (e.g., symbols not in the standard set) or if padding characters (=) appear in invalid positions.

BufferTooSmall

The provided output buffer is too small to hold the result.

This error is returned by the zero-allocation APIs (e.g., encode_into, decode_into) when the destination slice passed by the user does not have enough capacity to store the encoded or decoded data.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

Available on crate feature std only.

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 #99301)

Provides type-based access to context intended for error reports.

impl PartialEq for Error

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

impl Copy for Error

impl Eq for Error

impl StructuralPartialEq for Error
