Struct base64::alphabet::Alphabet

pub struct Alphabet { /* private fields */ }

An alphabet defines the 64 ASCII characters (symbols) used for base64.

Common alphabets are provided as constants, and custom alphabets can be made via from_str or the TryFrom<str> implementation.

let custom = base64::alphabet::Alphabet::new("ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/").unwrap();

let engine = base64::engine::GeneralPurpose::new(
    &custom,
    base64::engine::general_purpose::PAD);

Implementations

impl Alphabet

pub const fn new(alphabet: &str) -> Result<Self, ParseAlphabetError>

Create an Alphabet from a string of 64 unique printable ASCII bytes.

The = byte is not allowed as it is used for padding.

Trait Implementations

impl Clone for Alphabet

fn clone(&self) -> Alphabet

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Alphabet

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

Formats the value using the given formatter.

impl PartialEq for Alphabet

fn eq(&self, other: &Alphabet) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<&str> for Alphabet

type Error = ParseAlphabetError

The type returned in the event of a conversion error.

fn try_from(value: &str) -> Result<Self, Self::Error>

Performs the conversion.
