Struct FileOrFiles 

pub struct FileOrFiles {
    pub partition_index: u64,
    pub start: u64,
    pub length: u64,
    pub path_type: Option<PathType>,
    pub file_format: Option<FileFormat>,
}

Many files consist of indivisible chunks (e.g. parquet row groups or CSV rows). If a slice partially selects an indivisible chunk then the consumer should employ some rule to decide which slice to include the chunk in (e.g. include it in the slice that contains the midpoint of the chunk)

Fields

partition_index: u64

The index of the partition this item belongs to

start: u64

The start position in byte to read from this item

length: u64

The length in byte to read from this item

path_type: Option<PathType>

file_format: Option<FileFormat>

The format of the files along with options for reading those files.

Trait Implementations

impl Clone for FileOrFiles

fn clone(&self) -> FileOrFiles

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FileOrFiles

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

Formats the value using the given formatter.

impl Default for FileOrFiles

fn default() -> Self

Returns the “default value” for a type.

impl InputNode for FileOrFiles

fn type_to_node() -> Node

Creates an empty output node for a protobuf datum of this type.

fn data_to_node(&self) -> Node

Creates an empty output node for a protobuf datum with this value.

fn oneof_variant(&self) -> Option<&'static str>

Returns the name of the selected variant of a oneof field, if this is a rust enum used to represent a oneof field.

fn parse_unknown(&self, y: &mut Context<'_>) -> bool

Complete the subtrees of this datum in output that have not already been parsed using UnknownField nodes. Returns whether any such nodes were added.

impl Message for FileOrFiles

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 FileOrFiles

fn eq(&self, other: &FileOrFiles) -> 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 ProtoMessage for FileOrFiles

fn proto_message_type() -> &'static str

Returns the protobuf type name for messages of this type.
