Struct StripeInformation 

pub struct StripeInformation {
    pub offset: Option<u64>,
    pub index_length: Option<u64>,
    pub data_length: Option<u64>,
    pub footer_length: Option<u64>,
    pub number_of_rows: Option<u64>,
    pub encrypt_stripe_id: Option<u64>,
    pub encrypted_local_keys: Vec<Vec<u8>>,
}

Fields

offset: Option<u64>

the global file offset of the start of the stripe

index_length: Option<u64>

the number of bytes of index

data_length: Option<u64>

the number of bytes of data

footer_length: Option<u64>

the number of bytes in the stripe footer

number_of_rows: Option<u64>

the number of rows in this stripe

encrypt_stripe_id: Option<u64>

If this is present, the reader should use this value for the encryption stripe id for setting the encryption IV. Otherwise, the reader should use one larger than the previous stripe’s encryptStripeId. For unmerged ORC files, the first stripe will use 1 and the rest of the stripes won’t have it set. For merged files, the stripe information will be copied from their original files and thus the first stripe of each of the input files will reset it to 1. Note that 1 was choosen, because protobuf v3 doesn’t serialize primitive types that are the default (eg. 0).

encrypted_local_keys: Vec<Vec<u8>>

For each encryption variant, the new encrypted local key to use until we find a replacement.

Implementations

impl StripeInformation

pub fn offset(&self) -> u64

Returns the value of offset, or the default value if offset is unset.

pub fn index_length(&self) -> u64

Returns the value of index_length, or the default value if index_length is unset.

pub fn data_length(&self) -> u64

Returns the value of data_length, or the default value if data_length is unset.

pub fn footer_length(&self) -> u64

Returns the value of footer_length, or the default value if footer_length is unset.

pub fn number_of_rows(&self) -> u64

Returns the value of number_of_rows, or the default value if number_of_rows is unset.

pub fn encrypt_stripe_id(&self) -> u64

Returns the value of encrypt_stripe_id, or the default value if encrypt_stripe_id is unset.

Trait Implementations

impl Clone for StripeInformation

fn clone(&self) -> StripeInformation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StripeInformation

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

Formats the value using the given formatter.

impl Default for StripeInformation

fn default() -> Self

Returns the “default value” for a type.

impl Message for StripeInformation

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for StripeInformation

fn eq(&self, other: &StripeInformation) -> 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 TryFrom<&StripeInformation> for StripeMetadata

type Error = OrcError

The type returned in the event of a conversion error.

fn try_from(value: &StripeInformation) -> Result<Self>

Performs the conversion.
