Struct arrow_flight::FlightInfo

pub struct FlightInfo {
    pub schema: Vec<u8>,
    pub flight_descriptor: Option<FlightDescriptor>,
    pub endpoint: Vec<FlightEndpoint>,
    pub total_records: i64,
    pub total_bytes: i64,
}

The access coordinates for retrieval of a dataset. With a FlightInfo, a consumer is able to determine how to retrieve a dataset.

Fields

schema: Vec<u8>

schema of the dataset as described in Schema.fbs::Schema.

flight_descriptor: Option<FlightDescriptor>

The descriptor associated with this info.

endpoint: Vec<FlightEndpoint>

A list of endpoints associated with the flight. To consume the whole flight, all endpoints must be consumed.

total_records: i64

Set these to -1 if unknown.

total_bytes: i64

Trait Implementations

impl Clone for FlightInfo

fn clone(&self) -> FlightInfo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FlightInfo

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

Formats the value using the given formatter.

impl Default for FlightInfo

fn default() -> Self

Returns the “default value” for a type.

impl Message for FlightInfo

fn encode_raw<B>(&self, buf: &mut B) where
    B: BufMut, 

fn merge_field<B>(
    &mut self,
    tag: u32,
    wire_type: WireType,
    buf: &mut B,
    ctx: DecodeContext
) -> Result<(), DecodeError> where
    B: Buf, 

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, 

Encodes the message to a buffer.

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

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

fn decode<B>(buf: B) -> Result<Self, DecodeError> where
    Self: Default,
    B: Buf, 

Decodes an instance of the message from a buffer.

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

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

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

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, 

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

impl PartialEq<FlightInfo> for FlightInfo

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

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

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

This method tests for !=.
