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 new<F2>( encryption_algorithm: EncryptionAlgorithm, key_metadata: F2, ) -> FileCryptoMetaData

where F2: Into<Option<Vec<u8>>>,

Trait Implementations

impl Clone for FileCryptoMetaData

fn clone(&self) -> FileCryptoMetaData

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FileCryptoMetaData

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

Formats the value using the given formatter.

impl Hash for FileCryptoMetaData

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for FileCryptoMetaData

fn cmp(&self, other: &FileCryptoMetaData) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for FileCryptoMetaData

fn eq(&self, other: &FileCryptoMetaData) -> 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.

impl PartialOrd for FileCryptoMetaData

fn partial_cmp(&self, other: &FileCryptoMetaData) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl TSerializable for FileCryptoMetaData

fn read_from_in_protocol<T: TInputProtocol>( i_prot: &mut T, ) -> Result<FileCryptoMetaData>

fn write_to_out_protocol<T: TOutputProtocol>( &self, o_prot: &mut T, ) -> Result<()>
