Module prelude

Preconfigured engines for common use cases.

These are re-exports of const engines in crate::engine::general_purpose, renamed with a BASE64_ prefix for those who prefer to use the entire path to a name.

Examples

use base64::prelude::{Engine as _, BASE64_STANDARD_NO_PAD};

assert_eq!("c29tZSBieXRlcw", &BASE64_STANDARD_NO_PAD.encode(b"some bytes"));

Constants

BASE64_STANDARD

A GeneralPurpose engine using the alphabet::STANDARD base64 alphabet and PAD config.

BASE64_STANDARD_NO_PAD

A GeneralPurpose engine using the alphabet::STANDARD base64 alphabet and NO_PAD config.

BASE64_URL_SAFE

A GeneralPurpose engine using the alphabet::URL_SAFE base64 alphabet and PAD config.

BASE64_URL_SAFE_NO_PAD

A GeneralPurpose engine using the alphabet::URL_SAFE base64 alphabet and NO_PAD config.

Traits

Engine

An Engine provides low-level encoding and decoding operations that all other higher-level parts of the API use. Users of the library will generally not need to implement this.
