Struct Base64Codec 

pub struct Base64Codec { /* private fields */ }

Encodes and decodes Base64 byte strings.

This facade intentionally remains a whole-value codec backed by the base64 crate. Final partial quantum handling and optional = padding are facade/transcoder responsibilities, not part of the low-level quantum codec. Decoding is strict: each constructor accepts only its configured alphabet and padding policy, rejects whitespace and non-canonical trailing bits, and does not permit padded and unpadded partial groups to be interchanged. Complete three-byte groups such as TWFu need no = and are accepted by both padding policies.

Examples

use qubit_codec_misc::Base64Codec;

let codec = Base64Codec::standard();
assert_eq!(codec.encode(b"hello"), "aGVsbG8=");

Implementations

impl Base64Codec

pub fn standard() -> Self

Creates a standard Base64 codec that requires canonical padding for a partial final group. Complete groups need no =.

Returns

Standard Base64 codec.

pub fn standard_no_pad() -> Self

Creates a standard Base64 codec that rejects padding and accepts unpadded partial final groups.

Returns

Standard no-padding Base64 codec.

pub fn url_safe() -> Self

Creates a URL-safe Base64 codec that requires canonical padding for a partial final group. Complete groups need no =.

Returns

URL-safe Base64 codec.

pub fn url_safe_no_pad() -> Self

Creates a URL-safe Base64 codec that rejects padding and accepts unpadded partial final groups.

Returns

URL-safe no-padding Base64 codec.

pub fn encode(&self, bytes: &[u8]) -> String

Encodes bytes into Base64 text.

Parameters

• bytes: Bytes to encode.

Returns

Encoded Base64 text.

pub fn decode(&self, text: &str) -> MiscCodecResult<Vec<u8>>

Decodes Base64 text into bytes.

Parameters

• text: Base64 text.

Returns

Decoded bytes.

Errors

Returns MiscCodecError::InvalidBase64 when text uses another alphabet, violates this codec’s padding policy, contains whitespace, or has non-canonical trailing bits.
