Struct arrow_flight::sql::CommandStatementUpdate

pub struct CommandStatementUpdate {
    pub query: String,
    pub transaction_id: Option<Bytes>,
}

Represents a SQL update query. Used in the command member of FlightDescriptor for the the RPC call DoPut to cause the server to execute the included SQL update.

Fields

query: String

The SQL syntax.

transaction_id: Option<Bytes>

Include the query as part of this transaction (if unset, the query is auto-committed).

Implementations

impl CommandStatementUpdate

pub fn transaction_id(&self) -> &[u8]

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

Trait Implementations

impl Clone for CommandStatementUpdate

fn clone(&self) -> CommandStatementUpdate

Returns a copy of the value.

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

Performs copy-assignment from source.

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, Global>where Self: Sized,

Encodes the message to a newly allocated buffer.

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

impl PartialEq<CommandStatementUpdate> for CommandStatementUpdate

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