Enum ChunkDecryptionResult 

pub(crate) enum ChunkDecryptionResult {
    NeedMoreData,
    DecryptedChunk(Vec<u8>),
    FinalDecryptedChunk(Vec<u8>),
    Error(StreamDecryptionError),
}

Outcome of feeding one chunk of wire bytes to a StreamingDecryptor::update.

Variants

NeedMoreData

The decryptor needs more input bytes before it can produce plaintext.

DecryptedChunk(Vec<u8>)

A chunk of decrypted plaintext. Whether this is already authenticated is implementation-defined: chunked-AEAD STREAM authenticates per chunk and these bytes can be trusted; AES-CBC + HMAC authenticates only at finalize, and these bytes must be treated as untrusted until the terminal Self::FinalDecryptedChunk is observed.

FinalDecryptedChunk(Vec<u8>)

The final chunk of decrypted, authenticated plaintext.

Error(StreamDecryptionError)

Decryption failed. Discard the entire stream.
