Enum AlphabetError 

pub enum AlphabetError {
    InvalidByte {
        index: usize,
        byte: u8,
    },
    PaddingByte {
        index: usize,
    },
    DuplicateByte {
        first: usize,
        second: usize,
        byte: u8,
    },
}

Alphabet validation error.

Variants

InvalidByte

The alphabet contains a non-visible-ASCII byte.

Fields

index: usize

Byte index in the alphabet table.

byte: u8

Invalid byte value.

PaddingByte

The alphabet contains the padding byte =.

Fields

index: usize

Byte index in the alphabet table.

DuplicateByte

The alphabet maps more than one value to the same byte.

Fields

first: usize

First byte index.

second: usize

Second byte index.

byte: u8

Duplicated byte value.

Trait Implementations

impl Clone for AlphabetError

fn clone(&self) -> AlphabetError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AlphabetError

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

Formats the value using the given formatter.

impl Display for AlphabetError

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

Formats the value using the given formatter.

impl Error for AlphabetError

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)

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

impl PartialEq for AlphabetError

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