Struct CryptoMetadata 

pub struct CryptoMetadata {
    pub cek_table_ordinal: u16,
    pub algorithm_id: u8,
    pub encryption_type: EncryptionTypeWire,
    pub normalization_version: u8,
}

Per-column encryption metadata.

This metadata is present for each encrypted column and describes how to decrypt the column data.

Fields

cek_table_ordinal: u16

Index into the CEK table (0-based).

algorithm_id: u8

Encryption algorithm ID.

encryption_type: EncryptionTypeWire

Encryption type (deterministic or randomized).

normalization_version: u8

Normalization rule version.

Implementations

impl CryptoMetadata

pub const SIZE: usize = 5usize
