Struct Base64

pub struct Base64;

Standard Base64 encoder and decoder with padding.

This implementation follows the standard Base64 encoding as defined in RFC 4648, and includes padding characters (‘=’) when needed.

Standard Base64 Alphabet

The standard Base64 alphabet uses characters:

• ‘A’ to ‘Z’ (26 characters)
• ‘a’ to ‘z’ (26 characters)
• ‘0’ to ‘9’ (10 characters)
• ‘+’ and ‘/’ (2 characters)
• ‘=’ (padding character)

Examples

use ct_codecs::{Base64, Encoder, Decoder};

fn example() -> Result<(), ct_codecs::Error> {
    let data = b"Hello, world!";
    let encoded = Base64::encode_to_string(data)?;
    assert_eq!(encoded, "SGVsbG8sIHdvcmxkIQ==");

    let decoded = Base64::decode_to_vec(&encoded, None)?;
    assert_eq!(decoded, data);
    Ok(())
}

Trait Implementations

impl Decoder for Base64

fn decode<'t, IN: AsRef<[u8]>>( bin: &'t mut [u8], b64: IN, ignore: Option<&[u8]>, ) -> Result<&'t [u8], Error>

Decodes text data back into its binary representation.

fn decode_to_vec<IN: AsRef<[u8]>>( encoded: IN, ignore: Option<&[u8]>, ) -> Result<Vec<u8>, Error>

Decodes text data and returns the result as a Vec.

impl Encoder for Base64

fn encoded_len(bin_len: usize) -> Result<usize, Error>

Calculates the length of the encoded output for a given binary input length.

fn encode<IN: AsRef<[u8]>>(b64: &mut [u8], bin: IN) -> Result<&[u8], Error>

Encodes binary data into a text representation.

fn encode_to_str<IN: AsRef<[u8]>>( encoded: &mut [u8], bin: IN, ) -> Result<&str, Error>

Encodes binary data and returns the result as a string slice.

fn encode_to_string<IN: AsRef<[u8]>>(bin: IN) -> Result<String, Error>

Encodes binary data and returns the result as a String.
