Module base64

Base64 related macros

Modules

alphabet

Provides Alphabet and constants for alphabets commonly used in the wild.

display

Enables base64’d output anywhere you might use a Display implementation, like a format string.

engine

Provides the Engine abstraction and out of the box implementations.

prelude

Preconfigured engines for common use cases.

read

Implementations of io::Read to transparently decode base64.

write

Implementations of io::Write to transparently handle base64.

Enums

DecodeError

Errors that can occur while decoding.

DecodeSliceError

Errors that can occur while decoding into a slice.

EncodeSliceError

Errors that can occur while encoding into a slice.

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.

Functions

decodeDeprecated

Decode base64 using the STANDARD engine.

decode_engineDeprecated

Decode from string reference as octets using the specified Engine.

decode_engine_sliceDeprecated

Decode the input into the provided output slice.

decode_engine_vecDeprecated

Decode from string reference as octets.

decoded_len_estimate

Returns a conservative estimate of the decoded size of encoded_len base64 symbols (rounded up to the next group of 3 decoded bytes).

encodeDeprecated

Encode arbitrary octets as base64 using the STANDARD engine.

encode_engineDeprecated

Encode arbitrary octets as base64 using the provided Engine into a new String.

encode_engine_sliceDeprecated

Encode arbitrary octets as base64 into a supplied slice.

encode_engine_stringDeprecated

Encode arbitrary octets as base64 into a supplied String.

encoded_len

Calculate the base64 encoded length for a given input length, optionally including any appropriate padding bytes.
