Struct parquet_format::FileCryptoMetaData

pub struct FileCryptoMetaData {
    pub encryption_algorithm: EncryptionAlgorithm,
    pub key_metadata: Option<Vec<u8>>,
}

Crypto metadata for files with encrypted footer *

Fields

encryption_algorithm: EncryptionAlgorithm

Encryption algorithm. This field is only used for files with encrypted footer. Files with plaintext footer store algorithm id inside footer (FileMetaData structure).

key_metadata: Option<Vec<u8>>

Retrieval metadata of key used for encryption of footer, and (possibly) columns *

Implementations

impl FileCryptoMetaData

pub fn read_from_in_protocol(
    i_prot: &mut dyn TInputProtocol
) -> Result<FileCryptoMetaData>

pub fn write_to_out_protocol(
