codec

Codec stands for Coder and Decoder. It refers to the process of:

• Encoding: Converting data into a specific format
• Decoding: Converting data from a specific format back into a form that preserves the original content

Codec is not responsible for:

• Serialization (e.g., json, toml, yaml)
  • Use the std/serde module
• Compression (e.g., lz4, zlib)
  • Use the std/cede module
• Cryptography (e.g., hashing, encryption)
  • Use the runtime/crypto module

Purpose

A codec facilitates data transformation, especially when sending or writing data in a specific format.

Use Cases

• Transferring data across network boundaries
• Saving data to disk
• Improving query performance
