Struct Base64QuantumCodec 

pub struct Base64QuantumCodec { /* private fields */ }

Encodes and decodes one complete Base64 quantum.

A quantum maps exactly three raw bytes to four Base64 units. It does not handle final short input groups or = padding; callers that process streams must finalize those cases in a transcoder or facade layer.

Implementations

impl Base64QuantumCodec

pub fn standard() -> Self

Creates a standard-alphabet Base64 quantum codec.

Returns

Standard Base64 quantum codec.

pub fn url_safe() -> Self

Creates a URL-safe-alphabet Base64 quantum codec.

Returns

URL-safe Base64 quantum codec.

Trait Implementations

impl Clone for Base64QuantumCodec

fn clone(&self) -> Base64QuantumCodec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Codec for Base64QuantumCodec

fn min_units_per_value(&self) -> NonZeroUsize

Returns the four Base64 units needed for one complete quantum.

fn max_units_per_value(&self) -> NonZeroUsize

Returns the four Base64 units needed for one complete quantum.

unsafe fn decode_unchecked( &self, input: &[u8], index: usize, ) -> Result<([u8; 3], NonZeroUsize), Self::DecodeError>

Decodes one complete four-unit Base64 quantum.

unsafe fn encode_unchecked( &self, value: &[u8; 3], output: &mut [u8], index: usize, ) -> Result<usize, Self::EncodeError>

Encodes one complete three-byte Base64 quantum.

type Value = [u8; 3]

Logical value decoded from or encoded into the buffer.

type Unit = u8

Buffer unit used by the encoded representation.

type DecodeError = MiscCodecError

Error reported when decoding malformed units.

type EncodeError = MiscCodecError

Error reported when encoding an unsupported value.

impl Copy for Base64QuantumCodec

impl Debug for Base64QuantumCodec

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

Formats the value using the given formatter.

impl Default for Base64QuantumCodec

fn default() -> Self

Creates a standard-alphabet Base64 quantum codec.

impl Eq for Base64QuantumCodec

impl PartialEq for Base64QuantumCodec

fn eq(&self, other: &Base64QuantumCodec) -> 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.
