Module codec 

Structs

PostcardCodec

Postcard-based codec (compact binary serialization).

Traits

ObjectCodec

Trait for serializing and deserializing logical objects to/from bytes.

Functions

decrypt_block_to_plaintext

Read a block, extract envelope, decrypt, and return the raw plaintext bytes (before deserialization into a typed object). Used by the object cache.

prepare_encrypted_block

Encrypt raw data and pack it into a block-sized buffer (without writing to store). Returns the ready-to-write block bytes.

prepare_encrypted_object

Serialize, encrypt, and pad a typed object into a block-sized buffer (without writing to store). Returns the ready-to-write block bytes.

read_encrypted_object

High-level helper: read a block, extract envelope, decrypt, deserialize.

read_encrypted_raw

Read and decrypt raw bytes (for file data chunks).

write_encrypted_object

High-level helper: serialize a typed object, encrypt it, pad to block size, and write.

write_encrypted_raw

Write raw encrypted bytes (for file data chunks that are already raw bytes).
