Type Alias Base64Padded

pub type Base64Padded = Base<64, true, true, false, Rfc4648>;

Base64 encoding with padding (=) enabled, using LUT decoding.

Ensures encoded output length is always a multiple of 4 characters.

Aliased Type

struct Base64Padded { /* private fields */ }

Implementations

impl<const PAD: bool, const CASE: bool> Base<64, true, PAD, CASE, Rfc4648>

pub const fn encoded_len(input_len: usize) -> usize

Returns the required output buffer size for encoding input_len bytes.

pub const fn encoded_len_padded(input_len: usize) -> usize

Returns the required output buffer size for encoding input_len bytes.

pub const fn decoded_len(input_len: usize) -> usize

Returns the required output buffer size for decoding input_len Base32 characters.

pub const fn decoded_len_stripped(input: &[u8]) -> usize

Returns the required output buffer size for decoding input_len Base32 characters.

Strips the padding. Otherwise decoded_len will calculate for the worst case.

pub const fn decode_from_slice(input: &[u8], output: &mut [u8]) -> Option<usize>

Decodes input into output, returning the number of bytes written. Uses a LUT when DEC_TABLE = true, otherwise falls back to linear search.

Returns None if it finds an invalid byte.

Panics

Panics if output is too small.

pub const fn encode_to_slice(input: &[u8], output: &mut [u8]) -> usize

Encodes input into output, returning the number of bytes written.

Panics

Panics if output is too small.

impl<const PAD: bool, const CASE: bool> Base<64, true, PAD, CASE, Rfc4648>

pub fn decode(input: &[u8]) -> Option<Vec<u8>>

Available on crate feature alloc only.

Decodes input into a Vec<u8>, returns None if invalid characters are found.

pub fn encode(input: &[u8]) -> String

Available on crate feature alloc only.

Encodes input into a String.

impl<const RADIX: usize, const LUT: bool, const PAD: bool, const CASE: bool, CODE> Base<RADIX, LUT, PAD, CASE, CODE>

misc. methods

pub const fn new() -> Self

Returns a new Base with the chosen generics.

pub const fn with_radix<const NEW_RADIX: usize>( self, ) -> Base<NEW_RADIX, LUT, PAD, CASE, CODE>

Change the radix while keeping everything else the same.

pub const fn with_lut<const NEW_LUT: bool>( self, ) -> Base<RADIX, NEW_LUT, PAD, CASE, CODE>

Toggle LUT usage while keeping everything else the same.

pub const fn with_pad<const NEW_PAD: bool>( self, ) -> Base<RADIX, LUT, NEW_PAD, CASE, CODE>

Toggle padding while keeping everything else the same.

pub const fn with_case<const NEW_CASE: bool>( self, ) -> Base<RADIX, LUT, PAD, NEW_CASE, CODE>

Change the case sensitivity while keeping everything else the same.

pub const fn with_encoding<NewCode>( self, ) -> Base<RADIX, LUT, PAD, CASE, NewCode>

Change the encoding scheme while keeping everything else the same.
