Struct StandardKeyMetadata 

pub struct StandardKeyMetadata { /* private fields */ }

Standard key metadata for Iceberg table encryption.

Contains the Data Encryption Key (DEK), AAD prefix, and optional file length. Byte-compatible with Java’s StandardKeyMetadata via Avro serialization.

Wire format: [version byte (0x01)] [Avro binary datum]

Implementations

impl StandardKeyMetadata

pub fn new(encryption_key: &[u8]) -> Self

Creates a new StandardKeyMetadata.

pub fn with_aad_prefix(self, aad_prefix: &[u8]) -> Self

Adds an AAD prefix.

pub fn with_file_length(self, length: u64) -> Self

Adds a file length.

pub fn encryption_key(&self) -> &SensitiveBytes

Returns the plaintext Data Encryption Key.

pub fn aad_prefix(&self) -> Option<&[u8]>

Returns the AAD prefix.

pub fn file_length(&self) -> Option<u64>

Returns the optional file length.

pub fn encode(&self) -> Result<Box<[u8]>>

Encodes to Java-compatible format: [0x01] [Avro binary datum]

pub fn decode(bytes: &[u8]) -> Result<Self>

Decodes from Java-compatible format.

Trait Implementations

impl Clone for StandardKeyMetadata

fn clone(&self) -> StandardKeyMetadata

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for StandardKeyMetadata

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for StandardKeyMetadata

fn eq(&self, other: &StandardKeyMetadata) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
