Module codec 

Data encoding and decoding abstractions.
codec::{crypto, hash} ◉

Extends: std::{hash}

---

Structured, algorithmic transformations of data representations.

Modules

crypto

Cryptographic primitives for encryption, authentication, and hashing.

hash

Hash functions and hashers for compact data fingerprints.

Macros

bitfield

🏗️ ▫️ 🫗 Defines a compact packed-field wrapper backed by an unsigned integer.

set

🏗️ ⊆ ▫️ Defines a compact set backed by an integer bit mask.

Structs

Adler32

🔀 Adler-32 checksum.

Base

🥡 A compile-time configurable radix-based encoding scheme.

BinTag4

🪪 🥡 A fixed four-byte binary tag.

BitfieldExample_docs_examples and (_docs_examples)

✨ ▫️ 🫗 🗃️ A compact packet header.

Crockford

🥡 The Crockford Base32 encoding, case-insensitive, remaps certain characters.

Rfc4648

🥡 The RFC 4648 standard encoding, used in Base16, Base32, and Base64.

Rfc4648Hex

🥡 The RFC 4648 hexadecimal-variant encoding, used in Base32.

Riff

🪪 🥡 RIFF tagged binary container operations.

RiffChunk

🪪 🥡 A borrowed RIFF chunk.

RiffChunkIter

🪪 🥡 🔄 An iterator over borrowed RIFF chunks.

Enums

CompressionMode

🥡 The type of compression applied to data.

EncodingMode

🥡 The primary mode for data encoding.

RiffError

🪪 🥡 🚩 RIFF parsing error.

Type Aliases

Base16

🥡 Base16 standard encoding (hex), with linear search. Case-insensitive.

Base32

🥡 Base32 standard encoding, using LUT decoding. Case-sensitive.

Base64

🥡 Base64 standard encoding, using LUT decoding. Case-sensitive.

Base32Crockford

🥡 Base32 Crockford encoding. Case-insensitive, remaps O → 0, I/L → 1.

Base32Hex

🥡 Base32Hex uses RFC 4648 hex-encoding (0-9 A-V instead of A-Z 2-7).

Base32Padded

🥡 Base32 encoding with padding (=) enabled, using LUT decoding.

Base64Padded

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