Fields

header_length: Option<u64>

content_length: Option<u64>

stripes: Vec<StripeInformation>

types: Vec<Type>

metadata: Vec<UserMetadataItem>

number_of_rows: Option<u64>

statistics: Vec<ColumnStatistics>

row_index_stride: Option<u32>

writer: Option<u32>

Each implementation that writes ORC files should register for a code 0 = ORC Java 1 = ORC C++ 2 = Presto 3 = Scritchley Go from https://github.com/scritchley/orc 4 = Trino

encryption: Option<Encryption>

information about the encryption in this file

calendar: Option<i32>

software_version: Option<String>

informative description about the version of the software that wrote the file. It is assumed to be within a given writer, so for example ORC 1.7.2 = “1.7.2”. It may include suffixes, such as “-SNAPSHOT”.

Implementations

impl Footer

pub fn header_length(&self) -> u64

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

pub fn content_length(&self) -> u64

Returns the value of content_length, or the default value if content_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 row_index_stride(&self) -> u32

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

pub fn writer(&self) -> u32

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

pub fn calendar(&self) -> CalendarKind

Returns the enum value of calendar, or the default if the field is unset or set to an invalid enum value.

pub fn set_calendar(&mut self, value: CalendarKind)

Sets calendar to the provided enum value.

pub fn software_version(&self) -> &str

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

Trait Implementations

impl Clone for Footer

fn clone(&self) -> Footer

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Footer

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

Formats the value using the given formatter.

impl Default for Footer

fn default() -> Self

Returns the “default value” for a type.

impl Message for Footer

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<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, 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<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, 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<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes an instance of the message from a buffer.

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

where B: Buf, Self: Default,

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

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

where B: Buf, Self: Sized,

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

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

where B: Buf, Self: Sized,

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

impl PartialEq for Footer

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

This method tests for self and other values to be equal, and is used by ==.

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

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